spine below ; on the fourth leg the protarsus is armed with 

 some half-dozen antero-inferior spines. The tarsi of both 

 palpi and legs are apically spined below, the spines in- 

 creasing in number with the disappearance of the scopula, 

 so that on the fourth tarsus the distal half of the segment is 

 spinous ; the upper claws on the legs and palpi are armed 

 with one long spine, with usually a minute spinule as well, 

 rarely there are two longish spines. 



The sternum and labium are as in Aganippe subtristis ; 

 the maxillae are spinous at the base and the mandible is 

 armed below with 7 (8) internal, 9 external teeth, and an 

 intermediate line of 10 teeth ; the tubercular teeth of the 

 rastellum practically as in Aganippe suhtristia.

AnidiopS, gen. nov. 



Closely allied to Idiosoma in the majority of its characters, 

 but differing in having the abdomen covered above and 

 below with a clotliing of longish hairs intermixed above with 

 spines, and in the arrangement of the eyes, the formula of 

 which is a little less like that of Idiops. For example, the 

 anterior lateral eyes (the front pair), although situated on the 

 anterior margin of the carapace, are nevertheless separated 

 by a space wliich is about equal to their diameter; again, the 

 distance between the anterior medians is at least equal to 

 their diameter, and the posterior medians are about twice 

 their diameter from the anterior medians. 



Anidiops Manstridgei, sp. n. 



Colour (dry specimen) chestnut-brown, mandibles and 

 ocular area blacker. 



Carapace much longer than wide, its width (dry speci- 

 men !) much less than the distance between the hinder border 

 and the eye-cluster ; head wide, its width about equalling 

 the distance between the fovea and the anterior border, as in 

 Jiucgrfops latior (in Aganippe subtristis and Idiosoma sigil- 

 hitinii the head is considerably narrower than this distance). 



Mandible strong, broad at the base; rastellum as in the 

 other genera ; teeth below in three rows, 8, 9, 8. Maxillce^ 

 coxce of legs (especially of first and second pairs) , anterior part 

 of sternum, and labium covered thickly with pores elevated on 

 tubercles, indicating the ])rcscnce of a clothing, unhappily 

 rubbed off, of stout setie or, j)erhaps, spines. Maxilla armed 

 with short spines along the whole of the inner surface; femur 

 of palp with many stout setaj; tibia externally with 4
