where the teeth begin and the point of attachment of the 

 pecten. 



Measurements in niillinietres. — Total length 100, of cara- 

 pace 17, of tail o3'5 ; length of first segment 6, of fifth 12*5 ; 

 width of first 7''3, of fifth 5, of vesicle 4*6 ; width of brachiiim 

 5 7, of manus 14'5 ; length of hand-back 12*5, of movable 

 digit 15 5. 



A single male example from Ceylon {R. Templeton). 



In addition to the specimen described above, tliere is a 

 second in the Museum collection ticketed " India." It is a 

 female, and is ratlicr smaller than the male. The total length 

 is 89 millim., of which the tail is only 40 and the carapace 

 13; the vesicle is much narrower than the fifth caudal seg- 

 ment (3 : 4). The manus has the same form as in the male, 

 but the " ribs " are less pronounced. 



This species is most nearly allied to S. megacephalus. It 

 may be recognized by the form and structure of the hand, by 

 the relatively shorter space between the point of attachment 

 of the pcctines and the commencement of the teeth, the less 

 globular vesicle, &c. 



Family luridse. 

 Scorpiops tenuicauday sp. n. 



$ . Colour blackish chestnut, hands redder; vesicle and 

 tarsi pale. 



Carapace longer than the first three caudal segments, flat, 

 finely granular, the longitudinal groove in front of the ocular 

 tubercle very shallow and not laterally carinate ; the anterior 

 edge subtubercular ; the ocular tubercle polished, smooth, the 

 distance between the eyes equal to about twice a diameter ; 

 the posterior eye of the lateral series the smallest. 



Tergites nearly smooth, at most coriaceous or minutely 

 granular, with a smooth median crest ; the last with four 

 anteriorly abbreviated, finely granular keels. 



tSternites smooth, the last obsoletely costate posteriorly. 



Tail only two and a half times the length of the carapace, 

 posteriorly narrowed, the segments increasing in lengtli 

 posteriorly, the fifth as long as the third and the fourth, the 

 second about as wide as long, the first with 10 keels, the 

 second with 8 j the inferior keels smooth on the first segment 

 and becoming progressively more and more granular towards 

 the fourth ; the superior and superior-lateral keels finely den- 

 ticulate, the former terminating behind in a spiniform tootli 

 upon the second, third, and fourth segments, the intercarinal 

 spaces finely granular ; the fifth segment with its upper sur-
