•576 WALTER E. COLLINGE. 



segments 2-4 rounded terminally, those of 5-7 truncate, 

 posterior angles not produced. The notch or tooth on the 

 inner margin of the 1st segment is well developed and there 

 is a definite groove on the 2nd segment (fig. 7). Maxilli- 

 pedes (fig. 6) with the outer lobe elongated, at the base of 

 the multispinous process are three small spines and a larger 

 one on the outer border, on the inner border is a small pit from 

 whence there arise two spines, a short pointed one and an 

 •elongated one with spatulate end. The inner lobe is wide and 

 has three stout tooth-like spines. Uropoda (fig. 8) not 

 extending beyond the telson, ventrally flattened, basal plate 

 thick, convex, and raised dorso-laterally, posterior margin 

 obliquely cut away, antero-dorsal surface thickened; exopo- 

 dite short, extending to the inner margin of the basal plate, 

 endopodite short and broad, setaceous. Telson (fig. 9) rather 

 longer than the width of the posterior margin, not extending 

 beyond the ui'opoda, lateral margins strongly curved inwards, 

 expanded anteriorly and slightly raised in the mid-dorsal 

 line, posterior margin almost straight. 



Length 11 mm. 



Colour (in alcohol) horny brown with irregular dark 

 mottling. 



Habitat. — Grahamstown, September, 1915. (J. Hewitt.) 



Type. — In the Natal Museum. 



In its general shape and colour, and in the trilaminate 

 inner lobe of the 1st maxilla? this species shows a distant 

 relationship with C. longicaiTda, but it differs from that 

 species in the form of the cephalon, the presence of the tooth 

 and groove on the underside of the inner margin of the 1st 

 and 2nd mesosomatic segments, the more complicated and 

 •elongated lobes of the maxillipedes, and in the form of the 

 uropoda and telson.

 group of species which require separating into definite
