Pteropotls were dredged at seven stations and taken in surface collections at 



six. Those found in dredging are frequently different to the surface species at the 



same place ; this is probably due to the ocean currents carrying the light shells 



some distance. Cavolinia was by far the best represented genus found. At the 



deepest dredging in which pteropods were found, viz., 1,019 fathoms off the E. of 



Sth. America, a large deposit of " pteropod ooze" was discovered ; in which the 



only Heteropod was Atlanta per onii. A species of Carinaria was also found, 



but the surface collections are not thoroughly worked out ; and for the curious 



reason "of convenience " the Gasteropod Ianthina is included in this report, 



a circumstance which will probably result in the remarks being overlooked by most 



students of the Gasteropoda. The outline drawings are poor. — E. R. S.

The report, occupying nearly a hundred pages, is much inflated with remarks 

 compiled from other authors on such subjects as to the length of time snails can sub- 

 sist without food, agency of winds in distribution, &c, and the original work would 

 go into a much smaller space. For instance, the catalogue of the " Albatross " 

 shells is gone through, and then in a general summary, embracing other authors' 

 work, all the species are listed again. Mr. Stearns is to be congratulated on having 

 grouped no less than ten pseudo-species under Bulimulus mix. 



On the whole, it is an exhaustive summary of what is known respecting the 

 fauna of these islands. 



The "Albatross" work added 59 species to the fauna, about 15 of which were 

 new: why, however, the paper should be headed "with descriptions of new 

 species," when all of them have been described elsewhere, we are left to guess.
