124 MR. J. X. CUNNINGHAM ON MARINE FISHES [Jan. 18, 



Order Opisthobranchia. 

 Umbraculum MEDITERRANEUM. 



Umbrella mediterraneum Lamarck ; E. A. Smith, Marine 

 Mollusca of St. Helena, P. Z. S. 1890, p. 299. 



This large opisthobranch is common in the Mediterranean, and 

 occurs also at Madeira and the Cape Yerde Islands. It is not 

 mentioned by Melliss, but was first recorded from St. Helena by 

 E. A. Smith. I obtained a single specimen in the trawl at about 

 30 fathoms to the west of Jamestown ; it was alive and adult. 



Class CEPHALOPODA. 

 Octopus occidentalis. 



Octopus vulgaris var. americanus d'Orbigny, Moll. Cuba, p. 14, 

 tab. i. 



Octopus occidentalis Steenstr. MS., Hoyle, ' Challenger ' Report, 

 xvi. p. 77, 1886. 



This is doubtless the species mentioned by Melliss as Octopnis sp. 

 I obtained one small specimen which was brought to me by bo) 7 s 

 with some crabs from the shore rocks. It has not been identified 

 at St. Helena before, but the ' Challenger ' obtained one specimen 

 at Ascension. It occurs at Cuba, and was found by Alex. Agassiz 

 in the Pacific at the Galapagos Islands. My specimen was 

 identified by Mr. W. E. Hoyle, F.Z.S., Director of the National 

 Museum of Wales, Cardiff. 



ECHINODERMATA *. 

 Class ECHINOIDEA. 



ClDARIS TRIBULOIDES. 



Cidarites tribuloides Lamarck. 



Cidaris tribuloides Blainville, Zoopb., Diet. Sci. Nat. 1830. 



I caught several specimens of Cidaris in the trawl at 30 fathoms 

 to the west of Jamestown, and all that I brought home were 

 identified by Mr. Jeffrey Bell as of this species. It is not men- 

 tioned by Melliss, who says the thick-spined sea-egg of the island 

 is G. metularia Lamarck. This is not correct, C. metidaria being 

 the Pacific species, extending from the Sandwich Islands to the 

 Cape of Good Hope. C. tribuloides occurs also at Cape de Yerde, 

 on the west coast of Africa at Cape Palmas, at Florida, and on the 

 coast of Brazil. 



Tripneustes ventricosus. 



Tripneustes ventricosxis L. Agassiz, Mon. Echin. Scut. 1841. 

 Hippono'e esculenta A. Agassiz, Revision Echini, 1872-74. 

 This species is not mentioned by Melliss ; I am not quite sure 

 * Species identified by F. Jeffrey Bell, M.A., P.Z.S.
