by Verany are specifically distinct ; the differences between 

 them may be due to growth, or possibly to sex. 



Calliteuthis, Verrill, 1882. 

 Calliteuthis ocellata (Owen), Verrill. 



1881. Loligops is ocellata, Owen, Trans. Zool. Soc. Lond., vol. xi., part 5, 



pp. 139-143, pis. xxvi., figs. 3-8, xxvii, 



1882. Calliteuthis ,, Verrill, Cepli. N.E, Araer., p. 202. 



There can be no doubt that Sir Richard Owen's Loligopsis 

 ocellata is congeneric with Professor Verrill's Calliteuthis 

 reversa (loc. cit., p. 327) ; but the question whether they 

 belong to the same species can only be satisfactorily settled 

 by a comparison of the actual specimens, and must therefore 

 be left in abeyance. 



Ckanchia, Leach, 1827. 



Craiicliia Beinhardtii, Steenstrup. 



1855. LeacJiia Reinhai'dtii, Stp., Hectocotyldannelsen, p. 200. 



1%Q\. Cranchia ,, M, Overblik, p. 76 (8). 



1879. Loligopsis ,, Tryon, Man. Conch., vol. i., p. 165. 



1882. Cranchia ,, Brock, Zeitschr. f. wiss. Zool., Bd. xxxvi., p. 605, 



1884, Perothis ,, de Rochebr,, Monogr. Loligopsidse, p. 28 (20). 



This is a well-marked Cranchia, and there would be no 

 need for its mention here had not Tryon, without the least 

 show of reason, placed it under the genus Loligopsis. 



Chiroteuthis, d'Orbigny, 1839. 

 Chiroteuthis V6ranyi (Ferussac), d'Orbigny. 



1834". Loligopsis Veranyi, Feruss., Magasin d. Zool., pi. Ixv, 



1839. Chiroteuthis ,, d'Orb,, Ceph. Acet,, p. 235, pis. ii,, iv., figs. 17-23, 



This is the type of d'Orbigny's genus Chiroteuthis, and as 

 it is always known under this name, there would be no need 

 to mention it here except for the sake of completeness. 



Species of Uncertain Generic Position. 

 Loligopsis chrysophtalmos (Tilesius), d'Orbigny. 



i^epia chrysopjhtalmos, Tilesius, Krusenstern, Voy, Atlas, pi, xxxviii,,
