merely as a variety. Unfortimately, when the two fonns were 

 separated as distinct species by Joiibin, and later by Biirger, tbe 

 name anmdata was retained for tbe variety of the older authors 

 and new names were given to the type. IS'o doubt the reversion 

 by Biirger, in his IS'aples Monograph, to the original usage is in 

 accordance with the strict rule of nomenclatiu'e, yet one can but 

 deplore such shuffling of names as leading to endless confusion. 

 The present species is readily distinguished fi'om C. superla 

 by the curved ciliated grooves on the "neck," and by the 

 absence of a longitudinal white line on the ventral sm-face. 



Dredged in Valencia Harbour on both shell-beds and Ascidian 

 ground. Not ujLcommon in 1895 ; only one specimen taken in 

 1896. 



Carinella superba (Kolliker).

 Eiches (1893); Gamble (1896); {proparte) M'Intosh; Hubrecht. 



British examples of this species, which I have examined, 

 differ from the description of Biirger in the possession of a pair 

 of elongated black pigment spots (Pigmentflecke) on the anterior 

 margin of the head, like those described in C. lamjidensis, Joubin, 

 and C. nothns, Biirger. 



Two small individuals (about 25-35 mm. long), taken on the 

 "Wild Bank in Dingle Bay, resembled Biirger' s figure of C. notlms 

 (1895; pi. i., fig. 13) in shape of head also, as did another 

 individual measuring 12 mm. in which the usual ventral white 

 line was absent. But in all these the transverse white rings 

 were arranged as in C. superla, and I believe them to be merely 

 young individuals of that species. 



Commonly dredged in Yalencia Harboiu* (including the 

 ITullipore ground in Port Magee Channel), and occasionally 

 found under stones between tide-marks. Dredged also on Wild 

 Bank, Dingle Bay (15-20 fms.).
