One imperfect dead specimen fi'om the Ship Channel, in 30-40 

 feet, agrees very closely with Dr. Dall's figure 15, quoted above. 

 Neither the longitudinal ribs nor the spiral cingula are as prominent 

 as in the type specimen of Mangilia eritima Bush, from Cape Hat- 

 teras, N. C, and the granular effect is entirely concealed by erosion. 



Three other apparently undescribed species belonging to this 

 family were also found in the shell-sand. 



CEPHALOPODA. 



Two species of Octopus were taken, in 1898, both of which have 

 been previously recorded. The common large species is generally 

 listed as 0. vulgaris, but sometimes as 0. granulosus, or 0. rugosus 

 Bosc, under the belief that this West Indian and Florida species is 

 distinct from the European — a question that cannot be considered 

 as settled at present. They are certainly very closely related.
