SUCCINEA. 67 



Dr. DeKay also indicated a new species in his " Re- 

 port," under the name of Sucdnea lineata, but as it does 

 not appear in his final Report, we presume it was sub- 

 sequently regarded as merely a variety.

DESCRIPTION. 



Animal. " Whitish ; eyes, inferior tentacula, and a 

 line passing from the eyes disappearing under the shell, 

 black ; a gamboge-colored vitta is visible through that 

 part of the shell which is opposed to the mouth." 



Shell. Yellowish-white, or yellowish horn-color,

S. aperta is undoubtedly a speoies belonging to the Sandwich Islands, 

 described by me under the name of S. rotundata, in the Proceedings of the 

 Boston Society of Natural History, Vol. II. p. 182. Specimens of S. Nut- 

 talliana and S. oregoneiisis having been furnished by Mr. Lea, leave no 

 doubt as to their being decidedly well-marked species, and they will there- 

 fore be included among the other species described. Some other species 

 collected by Mr. Bartlett in Texas, have also been added. — G.]
