420 Deep-sea Trawling off the S.W. Coast of Ireland : 



scales. The right pectoral very small, about as long as the 

 eye ; the left pectoral is reduced to a minute ray. The ven- 

 trals, also, are small, but the extremities of their middle rays 

 extend backwards to the anal fin. The dorsal and anal 

 terminate immediately in front of the caudal. Scales of both 

 sides ctenoid, more so on the coloured than on the blind side. 

 Coloration uniform grey. 



This species is distinguished by characters which bring it 

 near to Solea vulgaris as well as to Solea variegata. From the 

 former it is separated by the rudimentary structure of its 

 pectoral fins, from the latter by the number of its fin-rays, by 

 its much smaller scales, and by its coloration. Unfortunately 

 only one specimen was obtained, nearly 6 inches long, at a 

 depth of 150 fathoms. It is in a perfect state of preserva- 

 tion. 



MOLLUSCA. By Edgar A. Smith. 



Of the twenty-four species enumerated in the following 

 list, nearly all were obtained by the ' Porcupine ' expedition 

 off the west coast of Ireland or in other parts of the Nortli 

 Atlantic, and have been recorded by Jeffreys in his series of 

 Reports in the Proc. Zool. Soc. 1878, 1879, 1881-85. It 

 would therefore be of little use now to give references and 

 distribution in full, which may be obtained by consulting the 

 papers referred to. The collection only affords slight addi- 

 tional evidence with regard to geographical and bathymetrical 

 considerations. 



The fine Dentalium and Sipho, the Lyonsiella, and the new 

 Cuspidaria are perhaps the most interesting of the additions 

 to the Museum collection.
