Taking these facts into consideration we cannot see 

 that there is any ground for regarding the Monaco 

 specimens as being specifically distinct from the one from 

 Messina, examined by us, and this again differs from 

 Appellors type only in characters which are dependent on 

 difference in age. We, therefore, regard C. cyprinoides as 

 a synonym of C. fimbj'iatiis. 



It must be remembered, however, that the specimens 

 examined by Joubin had undergone severe maceration by 

 the gastric juices of the dolphin from whose stomach 

 they were taken and that he only had for comparison 

 with them the figures and description of a much smaller 

 example. Hence he was led to attach more importance 

 to the apparent differences than they deserved. 



Calliteuthis nevroptera, Jatta ('96, p. 118, pi. 31, 

 figs I — 10). 



Unfortunately the type specimen of Dr. Jatta's species 

 appears to have been dissected and the parts not pre- 

 served. The principal differences between his published 

 description and our specimen are as follows : — 



The fin in Jatta's specimen extends along two-thirds 

 of the mantle, while in ours it is present along practically 

 the whole length of the mantle. This difference is probably 

 accounted for by the fact that ours is larger and more 

 mature. The tentacular arms are scarcely clubbed in our 

 specimen, the dilatation being of the slightest. The mar- 

 gin of the ocular opening is not perfectly round, as in 

 Jatta's example, but bears a notch at its antero-ventral 

 border ; this is exactly the same on both right and left 

 sides. The transparent elliptical disc behind the eye, 

 referred to by Jatta, is not pronounced in our specimen. 

 There is on the left side, behind the eye, a paler area, 

 somewhat reniform in shape, its concave face turned to the
