 Comanthus (Bennettia) samoana, A. II. Clark. 



Comanthus (Coimoithus) samoana, A. H. Clark, Proc. U.S. 

 Nat, Mas., xxxvii., 1909, p. 30 (Samoa). 



There was contained in the collection one specimen from Ugi, 

 with twenty arms 60 mm. long ; three of the nine II Br series 

 present are 2 instead of 4 (3 + 4) as usual ; on one ray, which 

 bears two II Br series, there is a HI Br series, developed 

 •externally. 



This species has a peculiar roughness to the touch, due to the 

 development of long spines on the outer pinnule segments, which 

 makes it distinguishable by a characteristic harsh and dry feeling 

 from Comanthus parvicirra ; it has more numerous and stouter 

 -cirri than the latter, and the centrodorsal is larger, encroaching 

 •further on the I Br series than does that of C. parvicirra. 



Comanthus (Vania) annulata {Bell). 



There is a specimen of this species at the British Museum 

 which was collected by H.M.S. "Penguin" at the Solomon 

 Islands.
