This form may be distinguished from other African species in which 
the postfrontal crest is distinctly developed, by the following charac¬ 
ters :—From T. perlata, M. Edw., which is found at the Cape and 
Port Natal, by the wider transverse carapace, which is more dilated at 
the branchial regions, and not dorsally granulated near the antero¬ 
lateral margins, and by the form of the orbit, whose inferior margin 
is regularly concave (not as in specimens referred to T. perlata in the 
Museum collection), abruptly angulated near the interior sub ocular 
lobe. From T. inflata , M. Edw., by the less convex carapace, straight 
postfrontal crest, and the granulated line which borders the antero¬ 
lateral margins of the carapace. T. aubryi , M. E., T. africana, A. M. 
E., and T. emarginata,, Kingsley, from the Gaboon, West Africa, and 
Port Natal, have an additional tooth between the exterior angle of the 
orbit and the postfrontal crest. In T. goudoti , M. E., from Madagas¬ 
car, the postfrontal crest is less developed, and the immobile finger of 
the chelipedes forms more or less of an angle with the inferior margin 
of the palm. Another species from Madagascar, T. madagascariensis , 
A. M. E., which has not, I believe, been figured, is distinguished by 
the lesser development of the postfrontal crest and the straighter 
fingers of the chelipedes, which meet along their inner margins. In 
the West African T. bciyoniana , T. ancliietce, and T. dubia , Brito 
Capello, the lateral epibranchial tooth is more developed. In T. limulct 
Hiigendorf, from Senegambia, the postfrontal crest is less distinctly 
developed near the lateral epibranchial teeth, behind which, in the 
males, are indications of two other teeth. 
3. A List of the Lepidoptera collected by Mr. H. H. Johnston 
DURING HIS RECENT EXPEDITION TO KlLIMA-NJARO. By F. D. 
Godman, F.R.S., &c. 
Mr. Johnston’s collection of Lepidoptera contains 61 specimens, 
including 27 species ; of the latter there are 21 species of Khopalocera 
and 6 of Heterocera. Of the Khopalocera I have described three 
species as new, and a fourth, a Chrysophanus , of which only one 
specimen of a female is in the collection, remains unnamed, though 
it too is probably .new. This small collection therefore contains 
nearly twenty per cent, of novelties, which must be considered a high 
proportion. 
But so small is the series that I do not think any comparison of 
the Lepidopterous fauna of this region with that of the rest of 
Africa can be entered upon with advantage. Suffice it to say that 
by far the majority of the species are widely distributed African 
ones; that there is a northern element, as shown in Colias edusa,
