Explanatory Notes on the Catalogue

Format

I have attempted to reproduce the Nuttall catalogue as a document historically faithful to the original work. In the left-hand column of each page is the catalogue as originally handwritten, including all remarks by Nuttall or his colleagues at Cambridge. Nuttall skipped the numbers 1555, 2101, and 3245-3254. These omissions are noted in the text. I found that the following original catalogue numbers needed to be rearranged: 2211, 2327-2344, 2746, 2905, and 3412 were repeated for completely unrelated collections and I have renumbered them, respectively, 2211Z, 2327Z-2344Z, 2746Z, 2905Z, and 3412Z. Nuttall misnumbered the catalogue item 1242 as 1142, which I have corrected.

At the Molteno Institute, Cambridge University, I was given various notebooks, including an almost complete one-volume copy of the tick catalogue that belonged to Nuttall. Professor Bruce Newton of the Molteno Institute graciously allowed me to deposit this material with Nuttall's tick collection at the British Museum (Nat. Hist.). Among these documents was a notebook entitled "Ticks. Collections Sent Away," which contains the names and addresses of numerous persons (usually parasitologists, teachers, and naturalists), the ticks they received, and the Nuttall number from which the ticks were taken. I have indicated these donations in the remarks section of the original catalogue column because they are part of Nuttall's original records although not so entered into his catalogue.

Nuttall often indicated the date he replied to the donor of a collection (i.e., R.14.VII.1914). In addition, he often entered the abbreviation of an author of a species name (i.e., Ambly. cohaerens Dö.). I have deleted reply dates and abbreviations. Throughout the catalogue he abbreviated names of tick genera, such as Ambly., Boo., Haem., and Hyal. I have given complete names for all tick genera. Also, in some but not

all instances, Nuttall cited a given collection as follows:

N3077 Aponomma trimaculatum 's, N's Ti) ♂ S (ii) N's

I have eliminated the redundant use of (i) and (ii). With these exceptions and a few minor corrections, all data appearing in the left-hand column are as they appeared in the original version of Nuttall's catalogue.

In his catalogue, Nuttall arranged collection data in seven general categories for each entry as follows: (1) Nuttall number, (2) tick determination, (3) host, (4) locality, (5) date, (6) collector, and (7) remarks. Entry (1) is always present and (2) is rarely absent. The remaining categories are usually included.

In the updated catalogue column, I have added to category (1) a Rocky Mountain Laboratories (RML) number. This number will allow these records to be added into the SELGEM (the acronym derived from SELF-GEnerating Master) information retrieval system of the National Museum of Natural History, Smithsonian Institution. This is a generalized system for information storage, management, and retrieval especially suited for collection management in museums. Often Nuttall neglected to list the number of specimens in a collection. I have added this information to the tick determination using the standard characters:♂ = male, female, N = nymph, and L = ? = larva. Host data are indicated by current species designation whenever possible. Common names are used when applicable or when no other choice is available. Specific localities are given coordinates whenever possible, but where the localities are large areas (viz Queensland, Australia; South Africa), no coordinates are given. I have used the more readily recognizable names of localities rather than the less common, albeit more correct, names. example, I have used Algiers instead of Alger and Cairo instead of Al-Qahirah.
