South African Crustacea. 251 



Adams and White for their Borneo specimen give the measure- 

 ments : "Carapace about an inch in length, and half an inch 

 wide." Our specimen is much smaller, the carapace being only 

 7mm. long andabout 6mm. between the apices of the antero-lateral 

 pair of denticles. The length indeed is rather less than 7 mm. in the 

 central line in consequence of the deep frontal notch. From the 

 advanced points of this notch the very oblique margin on 

 either side is finely denticulate, ending in a cavity bounded by 

 the comparatively large antero-lateral denticle. As in Lyreidus, 

 the third and fourth joints of the third maxillipeds are long and 

 narrow, but here the fourth joint is not longer than the third. 

 The three terminal joints are very small.

CRYPTODROMIA MICRON YX, n. sp. 

 Plate OIL 



The present species by its globosity is suggestive of Alcock's 

 Sphaerodromia, by the broad foiirth joint in the first four peraeopods 

 it points to Stimpson's Petalomera, but by its characters generally I 

 incline to leave it in Cryptodromia.
