What distinguishes the present species in particular are the 

 various depressions on the thorax, the entirely vertical position 

 of the posterior lateral eyes, the thin raised margin which surrounds 

 the thorax and abdomen, and the long seta with very numerous small 

 segments. Telyph. spinimanus, Lucas, of unknown habitat, is very 

 closely allied to our species, but the feet and palpi are in proportion 

 to those of ours shorter, and the tarsi of the first pair of feet not 

 so numerous. Another still more closely allied species is described 

 by Mr. H. C. Wood from China as Telyph. Stimpsonii (Proc. Acad. 

 Nat. Sci., Phil., 1861, p. 312) ; however the palpi, or cheliceres, 

 of this species are described as somewhat different, the denticulation 

 of the first moveable segment being very similar, but the third is 

 larger than the others, which is not exactly the case in our species. 

 The third segment has in T. Stimpsonii two minute spines above 

 and the terminal internal process is bifid, and the processes of the 

 fourth point are strongly serrated, while in the Assam species the 

 process is not divided, and the upper spines on the third, as well as 

 the strong serration of the fourth are absent. 



Loc. Assam. A large number of specimens of this species has been 

 sent by Messrs. Peel, Haughton and Gregory. These specimens vary 

 in size from half an inch to two inches, but they evidently are only 

 different stages of age of one and the same species. The young speci- 

 mens are sometimes of a quite uniform reddish brown colour and 

 have comparatively a longer tail than the old ones, while the spines 

 on the second (externally the 1st) segment of the palpi are not perfectly 

 developed. The species lives in damp places under stones, and is also 

 often met with in bath-rooms of houses, in company with true scorpions. 

 My colleague Mr. V. Ball informs me that he also procured a species 

 _ of a Telyplwnus in Western Bengal, it may be the same as the present, 

 but more likely another species which Koch describes from the East 

 Indies. Several specimens of this species also exist in the old collec- 

 tion of the Asiatic Society, but no record of localities exists.
