 This paper includes the description of mol- 

 lusks and brachiopods dredged on the Archl- 

 benthal plateau about the Hawaiian Islands, 

 as well as others obtained by the Albatross on 

 the western coast of America. A large num- 

 ber of siiecies hitherto uniigured are fully illus- 

 trated, and twenty-nine new species, four new 

 subgenera, two new genera, and one new family 

 are described. The types of all are in the Mu- 

 seum. Apart from descriptions of new forms the 

 most important feature of the paper is found 

 iu the anatomical data relating to the genera 

 Euciroa and Halicardia, Callocardia and Lyon- 

 siella, the subgenus Spergo of the Pleuroto- 

 niidre, Ancistrolepis of the Buccinidfe, and the 

 brachiopod genus Frieleia. It is shown that 

 in the genus Halicardia a peripedal septum is 

 formed by a thick outgrowth from the mantle 

 independent of the gills and siphonal septum : 

 that in Euciroa and Callocardia the gills differ 

 in very important characters from those of 

 their nearest relatives, and incidentally that 

 the subdivision of the pelecypods into orders 

 based on differences of the gills alone is unnat- 

 ural and can not be maintained. A peculiar 

 organ, the opisthopodium, discovered many 

 years ago in Plwladomya, by Owen, is shown 

 to exist also in JIalicardia, and is suitably 

 illustrated.
