nombreuses petites taclies rouges." I have examiued some rich 

 material from RoscofF, but I am unable to discover any difference 

 between specimens from this locality and those from Naples in 

 the antennae or the uropoda. Many of the specimens from 

 EoscofE are adorned with a very large number of fine greyish 

 dots ; in other specimens such dots are rather few in number, 

 and in some specimens they have completely disappeared, so 

 that they cannot be distinguished from those from Naples ; I 

 suppose that the greyish dots are red in living animals. It 

 may be added that specimens from Le Croisic and Concarneau 

 presented similar dots. The absence of such dots is not always 

 a specific difference, some specimens of Girolana iorealis being 

 adorned with hundreds of dots, while verj few or no dots are 

 found on other specimens preserved in spirit. 



Occurrence. — In my earlier paper it was stated that this 

 interesting form had been captured on the southern and western 

 coasts of G-reat Britain northwards at least to the Eirth of Clyde, 

 at the Channel Islands, lioscoff, south-western coast of Brittany,, 

 finally at Naples. A. 0. Walker records it from Bautry Bay, 

 west coast of Ireland. Mr. DoUfus's collection contains many 

 specimcDs from some localities on the south-western coast of 

 Brittany; for instance, five rather small animals taken on 

 " la voute palatine et orbite d'un Dauphin pris a Concarneau,"^ 

 and seven specimens in a Maja at Le Croisic. — Miss Richardson 

 (Proc. U.S. Mus. xxiii. p. 515) states that this species has been 

 taken in two places in the southern part of the United States, viz.,^ 

 " off South Carolina ; between the Delta of the Mississippi and 

 Cedar Keys, Florida." I am, however, inclined to believe that the 

 specimens in question belong to an undescribed species, and 

 the author does not say if she has compared them with European 

 specimens of C cylindracea.

The essential characters of the genus are given in the con- 

 spectus of the genera. 



Six species (not counting E. pontica, Czern.) live in the seas 

 of Europe. All are very similar in general aspect ; besides, the 

 males of some of the species differ in certain conspicuous features 

 more from their females than examples of the latter sex be- 

 longing to different species. Eyes, antennulse, flagellum of 

 antennae, relative length of abdomen, and sometimes the uropoda
