130 F. Stoliczka — Notes on the j.ndlan Species of Tlielyphonus. [No. 2, 



The species which I have to notice from India, are : 



1. T. scalrinus, n. sp. — Cachar, Khasi hills, Assam, Sikkim. 



2. T. Assamensis, Stol. — Assam, Sikkim. 



3. T. (conf.) angustus, Lucas. — Sikkim, Martaban (Moulmein), and 

 Penan g. 



4. T. formosus, Butler. — Martaban (near Moulmein). 



5. T. indicus, n. sp. — South India, W. Bengal, and Jahore, North of 

 Singapore. 



6. jT. Beddo7?iei, n. sp. — South India (Anamallies) . 



I will make my descriptions as complete* as possible, and will not only- 

 give figures of single parts of the body, but also of the perfect specimens, 

 in order to facilitate the determination by identification and not by guess. 

 Figures of single parts are undoubtedly very useful, but they are not 

 sufficient ; they do not convey an exact idea of the relative proportions of 

 all the parts of the body, and without paying due regard to these, a really 

 reliable determination of Thelyplioni is in my opinion impossible. 



1. Theltphontjs scabeinus, n. sp. PL XII. Fig. 1. 



TJie li'liole upper surface granular ; length^ of the five terminal joints 

 of the cheliceres equalling the length of the first eight ahdominal segments ; 

 the length of last pair of feet equals exactly, or very nearly, the total length 

 of the cephalothorax and abdomen ; second joint of the cheliceres with five 

 spines, third ivith a spine on the upper and lower inner edge, and equal in 

 length to the fourth joint ; a sharp upper ridge connecting the central and 

 lateral eyes ; first lower segment of abdomen of moderate size, depressed, with 

 a broadly convex posterior edge. 



Hob. — Sikkim, Assam, Garo-, Khasi- and Cachar- hills. 



The cephalothorax is slightly convex, with the anterior ocular poi'tion 

 somewhat higher, but on the whole depressed and flattened, roundly obtuse in 

 front. The two anterior blackish eyes are separated by a moderately levated 

 smooth tubercle ; from its anterior edge proceeds a sharp ridge curving out- 

 ward, and running along the upper edge to the three lateral eyes, which are 

 pale yellow. The ocular portion is more densely and somewhat more coarsely 

 granular than the thoracic one ; the former has a longitudinal central groove, J 

 and parallel to it an indistinct elevation on either side, placed nearer 



* I know that few would take the trouble of reading them on account of their 

 length, but everybody, who has attempted to determine Arachnoids, will know that 

 a description, unless fully detailed, is luorthless for an accurate determination. 



t This length is of course measured as far as the joints can be opened without 

 disconnecting the articulation; it is not the aggregate length of the separate joints. 



J I shall speak of this as the cephalic groove, and of the one on the posterior half of 

 the cephalothorax as the thoracic groove and the lateral thoracic depressions.
