CEtrSTACEA. ■ 543 



In these specimens the carapace is very distinctly granulated over 

 its upper surface ; the chelipedes are hairy on their inner surface, 

 but are not ciliated on their margins ; the palm is not oarinated ; 

 the upper (mobile) finger has the blunt or quadrate tooth on its 

 inner margin mentioned by Eiippell as characteristic of the male of 

 Macroiphthalmus depressus ; the lower finger is slightly deflexed, 

 so as to form an angle with the lower margin of the palm. I have 

 already referred to JEhiplax hosdi in the earlier part of this Report. 

 The carapace is not quite so broad as in Ruppell's figure of M. depres- 

 ms, based on •& female specimen, and the upper orbital margin is 

 sinuated, not straight as in that figure ; so that I must regard M. 

 depressus as a distinct species. 



59. Dotilla fenestrata, Uilgendorf. 



Mozambique, between tide-marks (No. 227), eleven specimens, all 

 of them males. 



There is in the British-Museum collection a series of specimens of 

 both sexes of the allied D. sulcata (ForskSl), from the Ked Sea. 

 The distinctive characters pointed out by Hilgendorf are constant in 

 the two series. 



D. fenestrata has been hitherto a desideratum to the collection of 

 the Museum. Hitherto it has apparently been recorded only from 

 the east coast of Africa, where it ranges from Ibo to Natal, if (as 

 Hilgendorf notes, and as is doubtless correct) the specimens referred 

 by Krauss to D. sulcata belong to D. fenestrata. 



60. Carcinoplax integra. (Plate XLVIII. fig. C.) 



Th^ body and limbs are everywhere clothed with a short close 

 pubescence ; the antero-lateral margins of the carapace, the frontal 

 region above the anterior margin, and the chelipedes and limbs are 

 fringed with longer hairs. Carapace transverse, with the antero- 

 lateral margins entire and much shorter than the postero-lateral ; 

 the front is about one third the greatest width of the body, some- 

 what deflexed; its anterior margin nearly straight, with a very 

 small median notch ; the endostome without longitudinal ridges ; 

 the orbital margins entire, without teeth or fissures. The post- 

 abdomen (in the young female) has none of the segments coalescent, 

 at base it covers the whole width of the sternum. The eye- 

 peduncles are pubescent, lie closely within the transverse orbits, and 

 have a distinct black cornea ; the basal (or actual second) joint is 

 narrow and slender, and does not quite attain the front. The outer 

 maxiUipedes have a nearly quadrate merus-joint, with straight 

 anterior margin and rounded, not excavated, antero-internai angle. ' 

 The chelipedes are subequal and densely pubescent and hairy ; merus 

 short and trigonous, with a smaU blunt tooth or lobe near the distal 

 end of ■ the upper margin ; wrist somewhat angulated, but not 

 toothed on its inner margin ; palm about as long as the wrist, 

 rounded above and below ; fingers naked at the tips and meeting
