I am unable to distinguish the specimens of this species collected at the Caj^e of 

 Good Hope from the northern ones. There seems to be a number of northern species of 

 Spatangoids which extend to the Cape ; among them are to be mentioned also Brissopsis 

 Itjrifera, Spatangus raschi, and Schizaster fragilis.

I may state here that Lovenia elongata has been found in the Gulf of California by 

 Dr W. J. Fisher (Mus. Comp. Zool. Coll.), and is thus found associated on the west 

 coast of Central America with Lovenia cordiformis, while in the Philippine Islands it is 

 associated with Lovenia subcarinata.

Several of the specimens of this species collected by the Challenger are somewhat larger 

 than those previously known. The figures given show at a glance the characters which 

 distinguish this species. The profile view and the abactinal view are specially important 

 as showing the striking difference in the structure of the posterior extremity from that 

 of Lovenia elongata. The anal system is small (PI. XXXV." figs. 5, 6), and is placed 

 at the upper extremity of a slight depression above the subanal fasciole, placed entirely 

 on the sloping posterior extremity aljove the ambitus, in striking contrast to the large
