inconsiderable length, in male scarcely exceeding 1/3 of the 

 body. Endites of Ist pair of legs comparatively shorter 

 than in Ä. numidicus. Length of adult female, not including 

 the caudal filaments, 29 mm., of male 32 mm. 



Remarks. — This is undoubtedly a very distinct species, 

 differing from A. numidicus both in the characteristic shape 

 of the carapace, and in the number of caudal segments in 

 both sexes. The small size of the carapace, as compared 

 with the exposed part of the body, is more pronounced in 

 this form than in any other species with which I am 

 acquainted, the male especially being in this respect dis- 

 tinguished in a very marked degree (see fig. 4). 



Description of the female. 



The chief dimensions of an apparently fully grown 

 specimen are as follows: — 

 Total length of body, from the frontal margin to the . 



end of last caudal segment 29 mm. 



Median length of carapace 12 — 



Greatest width of same 13 — 



Length of exposed part of body 16 — 



Length of the caudal part 8^ — 



Length of caudal filaments 14 — 



The general form of the body (see fig. 1) appears rather 

 slender, at least when compared with the European species 

 A. cancriformis ; and in this respect it more resembles that 

 of A. numidicus, from which, however, it is at once dis- 

 tinguished by the peculiar shape of the carapace. 



The latter is very much depressed, more so than in 

 any other species with which I am acquainted, and, when
