Fasciolaria gigantea, subsp. reevei. — Dr. H, A. Pilsbry exhib- 

 ited specimens from Little Sarasota Bay aud Clearwater Harbor, 

 Fla., the former collected by Mr. Henry Hemphill, the latter by 

 Dr. J. W. Velie, who in sending a sj)ecimen to the Academy had 

 directed attention to the peculiarities of the form. Dr. Pilshry 

 stated that the specimens are referable to the form described by 

 Philippi' as Faseiolarla reevei Jonas. That form has been lost sight 

 of by later observers. Those authors who have noticed it have con- 

 sidered it to be a synonym of F. jj?';'?i.cej3S, a species of the Panamic 

 zoological province, from which it differs in the gradual decrease in 

 prominence of the sculpture with age aud the smooth operculum. 



It seems to be a local subspecies of F. gigantea, differing from 

 that by its much smaller size, the obsolescence or absence of nodes 

 on the last whorl, the longer and narrower anterior portion, etc. 

 The shell reaches a length of 24 cm., and is covered with a dark 

 cuticle, blackish-chestnut on the last whorl, yellowish-chestnut on 

 the spire. Under this cuticle and in the mouth the shell is pale 

 salmon-pink. Fine lirie may usually be felt deep in the aperture, 

 but they are not colored as in F. prlnceps.
