116 ECHINODERMA OF THE INDIAN MUSEUM, PART VII. 



Another specimen has the cirri XXXV, 27-29 ; there are fifty-one arms ; only 

 one of the division series (a IIIBr series) is 2 ; the division series as in the other 

 are strongly convex and well separated : the jiroximal pinnules are exactly as in 

 the other, 18 mm. to 21 mm. long. 



Habitat. — Kolumaduli, Maldives. 



Depth. — 38 fathoms.

Habitat. — Amboina ; Singapore ; Pnlau Ubin, Singapore ; ? Cochin China. 



Remarks. — The type of Aclinotnetra robustipinna preserved at Leyden 

 proves to be a specimen of some species of Himerometra, and is not an " Actino- 

 m.etra " at all ; in appearance it is exactly like the specimens of H. crassipinna 

 which I have examined from Singapore ; the IIIBr series throughout are 4 (3+4). 

 a rather unusual, though not at all an unknown condition. The pro.ximai 

 pinnules are very large and stout, the tip ending bluntly after a considerable re- 

 curve. So far as they are preserved the segments are all broader than long ; the 

 distal ends are not thickened or produced, though appearing slightly prominent 

 and a trifle swollen. One P, with eighteen segments seems to be complete. This 

 appears to be the same thing as Hartlaub's Antedon crassipinna, but the identifi- 

 cation cannot be certain because of the absence of all the cirri and of the pin- 

 nule tips. 



Hartlaub's specimen from Cochin China, which I examined at Hamburg, 

 appears to belong to a different species, but no material was available for critical 

 comparison.
