Eight males and females in Francis Bay ; two males off 

 Cape Agulhas in a depth of 80 m. ; seven males and females in 

 Algoa Bay. 

 1907. H. 0., Stimpson, Smithson. Misc. Coll., vol. xlix., 

 p. 144. 

 " Found at the Cape of Good Hope, in False Bay, on sandy 

 bottoms, in ten fathoms." Stimpson also remarks that " the 

 published figures of this species must in many respects be 

 imperfect, as they show great discrepancies."

Miers only expresses the opinion that this is possibly not 

 distinct from H. orbicidare, with which Doflein in 1904 unites 

 it, as a possible variety. 



1905. H. g., Stebbing, S.A. Crustacea, pt. 3, p. 50. 



No. 69, specimens sent by Dr. Gilchrist were taken in False 

 Bay, Eoman Eock, N.W. | N., | mile; depth 33 m. This 

 species has also been sent me by C. F. Beyers, Esq., taken 

 at low tide in False Bay. 

 1907. H. g., Stimpson, Smithson. Misc. Coll., vol. xlix., p. 144. 



Stimpson says: "The only specimen before us is a male," 

 and, after describing it, writes as follows: "This species is 

 certainly distinct from H. orbiculare, if the published figures 

 and descriptions of that species are to be relied upon. 

 Besides less important chai'acters, the sharp lateral teeth on 

 the hepatic region and the slenderness of the ischium-joint of 

 the outer maxillipeds will be sufldcient to distinguish it. Un- 

 fortunately we have no specimens of the true H. orbiculare 

 upon which to found a comparison, as the examples which 

 were taken at the Cape, and identified with that species at the 

 time, were all lost by accident. Our specimen was dredged 

 from a sandy bottom in twelve fathoms, in Simon's Bay, 

 Cape of Good Hope."
