1 It is not a little remarkable that this curious species should have remained 

 undisturbed for forty years in the genus Loligopsis, and that then within a 

 year no less than three genera should have been formed for its reception. It 

 is rather unfortunate that the name proposed by de Rochebrune, who has only 

 copied Verauy's, very unsatisfactory diagnosis, should have preference over 

 those suggested by Pfeffer and Verrill, who have added considerably to our 

 knowledge of this genus ; they have both, however, chosen names which were 

 preoccupied (see Gray, B.M.C., p. 63, and d'Orb., Moll, viv., p. 363). With 

 respect to the identity of the two forms figured by Verany, Prof. Steenstrup 

 informs me that he has had the opportunity of examining them both ; a 

 specimen of one (Verany, loc. cit., fig. h) was given by Krohn to Verany, by 

 Verany to Kolliker, and by Kolliker to Steenstrup, and is now in the Copen- 

 hagen. Museum ; of the other (fig. a). Prof. Steenstrup examined the original 

 specimen preserved in the Museum Senkenbergianum, Frankfort, and found
