NAJA MELANOLEUCA Hallowell. Black Cobra.
Small numbers of adults of the snake tick, Aponomma latum, were found on individual hosts of the above species; nymphs were also found on the black cobra. All specimens were taken during the dry season at Torit except that from Boaedon, which was col lected during the rainy season at Katire in the forested Imatong Mountains. These hosts are all large, poisonous snakes. Numerous specimens of the same and smaller snakes examined in Torit and other Districts of Equatoria were free of ticks. Ticks are usual ly found between the host's dorsal scales, especially just behind the neck, sometimes on the head, rarely on the venter.
In exceptional instances, the host may be literally covered with ticks of this species.
VARANUS N. NILOTICUS Laurenti.
Nilotic Monitor or Waran.
*Reptiles were identified by Dr. K. P. Schmidt, Emeritus Chief Curator of Zoology, Chicago Natural History Museum. Information on the same and other reptiles mentioned in the text was kindly given by Mr. A. Loveridge, Museum of Comparative Zoology, Harvard University, who has published a paper on snakes of Torit District (Sudan Notes and Records, 1955).
This large lizard is common in Equatoria Province, especially near streams and in association with trees. A few among many spec. imens examined yielded small to moderate numbers of nymphs and adults of the monitor lizard tick, Aponomma exornatum. A single lizard yielded a nymphal Amblyomma nuttalli and four nymphs and a male of A. marmoreum (group). The incidence of infestation is not high. Infested monitors were found in Torit, Juba, and Yei Districts.
VARANUS E. EXANTHEMATICUS Bosc.
Northern Savannah Monitor.
This monitor is less common than niloticus and fewer were examined. Two Torit hosts yielded a nymphal 1. nuttalli during the dry season and a number of adults and nymphs of Aponomma exornatum during the rainy season.
CHAMELEO G. GRACILIS Hallowell.
A nymph of the elephant amblyomma, A. tholloni was found on a chameleon at Lokila. Many other chameleons and hundreds of smaller lizards examined in eastern Equatoria Profince were free of ticks.
KINIXYS B. BELLIANA Gray. Bell's Eastern Hinged.Tortoise.
Land tortoises are fairly common on the east bank of Equatoria Province and are not infrequently tick infested. Tortoises must be anesthesized or killed in order to find ticks attached deep in the axillae, otherwise specimens are easily overlooked. A pair of adult H. truncatum was found on a Juba tortoise, another yielded numerous adults and nymphs of A. marmoreum (group). The latter species was found in small numbers on a Torit tortoise, and at Farajok and near Meridi two tortoises bearing a few adults of A. nuttalli were taken.
FRANCOLINUS CLAPPERTONI GEDGII Grant. Uganda Clapperton Francolin
These common savannah birds were one of our chief articles of diet and hundreds were rapidly examined for ticks. The three specimens found, all from Torit during the dry season, were a nymph of A. nuttalli, another of A. cohaerens (identification questionable), and a female H. hoodi hoodi.
NUMIDA MELEAGRIS MAJOR Hartlaub. Uganda Tufted Guinea Fowl
As many of these common savannah birds as of those mentioned above were briefly examined with equally unspectacular results. Only nymphs were found, all during the month of December. These were one A. cohaerens (identification questionable) at Ikoto, five A. variegatum at Kapoeta, and one Hyalomma sp. at Torit.
GUTTERA EDOUARDI SETHSMITHI Neumann. Blue spotted Forest Guinea Fowl
These handsome birds are confined to forest patches and open gallery forests and therefore very localized in the Sudan. The two specimens examined in Lotti Forest in April yielded eleven larvae and sixteen nymphs of H. parmata.
SPHENORHYNCHUS ABDIMII (Lichtenstein). Abdim's Stork
of several specimens examined at Torit during the dry season, one yielded two nymphs of H. hoodi hoodi and another two nymphs of A. variegatum and a male R. s. sanguineus. Large flocks of Abdim's storks feed in durra fields in Torit District, but they appear to be migrants or to have a wide range of feeding areas.
*Domestic birds are listed with DOMESTIC ANIMALS. Bird identifica tions were provided by Dr. A. L. Rand, Chief Curator of Zoology, Chicago Natural History Museum, who also kindly checked references to birds mentioned elsewhere in the text.
NEOTIS CAFRA DENHAMI (Children). Denham's Greater Bustard
In Torit District ten greater bustards from open savannah were examined during the dry season. A male A. lepidum and four male R. s. sanguineus were found on the head of one at Torit and eight males of the latter species were taken from the head of another at Ikoto.
LISSOTIS M. MELANOGASTER (Rüppell). Black_bellied Bustard
Search over a dozen black bellied bustards in Eastern and Torit Districts resulted in only three larvae and a nymph of A. variegatum at Kapoeta during the dry season. These birds are common in open grasslands and fields in Torit District and es. pecially numerous in Eastern District.
TURDUS LIBONYANUS CENTRALIS Reichenow. Great Lakes Kurrichane Thrush
A specimen examined at Obbo late in the dry season yielded a single nymph provisionally identified as A. cohaerens. TCHAGRA SENEGALA ERLANGERI (Neumann). Sudan Black_headed Tchagra
Several specimens were examined. One at Torit during the dry season was infested with a nymph of A. variegatum. This is one of the most common birds of the area.
INSECT IVORA (INSECTIVORES)
ATELERIX PRUNERI OWENI Setzer, 1953. Owen's Four-toed Hedgehog
*Mammal host identifications are based on Setzer's (1956) study of mammals (excluding bats) of the Sudan, a project resulting from col lections made for the present study of ticks and related studies of other ectoparasites. Bat hosts were identified by Mr. C. C. Sanborn, formerly Curator of Mammals, Chicago Natural History Museum.
