multi-articulated seta, and are therefore harmless. They also have 

 the feet much longer than the palpi, while in the scorpions the 

 contrary is the case. Lucas published, 1835, a monograph of the genus 

 in Guerins " Magasin de Zoologie," which is simply copied by Gervais 

 in Walkenaer's " Apteres," vol. iii. Koch "Die Arachniden" &c. 

 vol. x, and other authors, have since described several other species. 

 The North American ScoRPioxnxaE have been monographed in 1863 by 

 Mr. Wood (see Journ. Acad. Nat. Sc, Phil., 2nd ser., vol. ii, p. 358). 



The species of Telyplioni are all remarkably like each other, and it 

 is very difficult to find any striking distinctions between them. In 

 habits they are quite similar to the scorpions, living in damp places 

 under stones &c. ; not unusually they are met with in houses. 



Telyphonus Assamensis, Stol. Pi. XIX, Fig. l. 



Body depressed, all over finely granulated ; general colour above 

 dark brown, blackish on the thorax and palpi, paler on the abdomen 

 and feet ; below, the same parts respectively still paler and more dis- 

 tinctly reddish. 



The thorax is much longer than broad, surrounded with a thin, 

 raised margin ; its front part is sub-triangular, somewhat higher than 

 the rest. The anterior angle, near which the two central eyes are 

 situated is obtuse ; the central eyes themselves are slightly prominent 

 and separated from each other by a round smooth tubercle. The region 

 of the. lateral eyes is also slightly prominent, two eyes, of which the 

 lower is much the larger, being contiguous, and situated on the front 

 side of the prominence, while the third is the smallest and somewhat 

 more distant. The posterior part of the thorax which is nearly double 

 as long as the anterior has, on the surface, numerous depressions of 

 which a central longitudinal groove is the most conspicuous. 



The palpi are about as long as the abdomen, they are very stout. 

 The first moveable segment has 4 spines on the upper inner edge, 

 the last two have a common base and the outer one is the stronger ; 

 the upper anterior edge has only one spine, and the lower two subequal 

 ones on a common base. The second segment which is very obliquely 

 articulated to the first has one small spine on the lower front edge ; the 

 third has anteriorly one inner long process, and the fourth a smaller 

 internal one, but a much larger external, articulated and slightly 

 curved.
