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 vartegata. 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 Epaar A. Smirn. 
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 North 
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.
