South African Crustacea. 257 



with the subdorsal position of the fifth peraeopods, is found again in 

 the genus Grypachaeus, which Alcock instituted in 1895 for a member 

 of the Oxyrrhyncha, placing it in his subfamily Inachinae, a division 

 of the Mamaiidae. 



The specific name is chosen out of respect to my friend, Colonel 

 Alcock, F.E.S., whose writings on the Malacostraca can scarcely be 

 too highly valued.

 In this genus the eye-stalks are long and slender, the third 

 maxillipeds are juxtaposed at base, the fourth peraeopods are not 

 chelate ; in both sexes the telsoii is lop-sided to the left ; in the 

 female from the left side of the fourth segment a foliaceous lobe 

 forms a brood-pouch [see Alcock, pp. 24, 31, 1905].)

The small female specimen which I diffidently assign to this 

 species has a carapace only 8 mm. long, the chelipeds subequal, 

 setose, the second and third peraeopods also having long setae 

 on the upper and lower borders. The eye-stalks are subequal in 

 length to the peduncles of the second antennae a,nd are shorter 

 than the width of the front of the carapace.

A specimen partly dried, with chelipeds and ambulatory limbs 

 detached, seems near to P. ciliatus, Heller, as doubtfully re-described
