This species' nearest relative appears to be L. succincta 

 Newc. It is usually smaller, more cylindrical in outline and 

 the spire is decidedly less conical. 



Measurements of some of Gulick 's specimens are : 



Length 12.7, diam. 6.0, length of apert. 6.1 mm. Pupukea. 



Length 11.2, diam. 5.7, length of apert. 5.6 mm. Pupukea. 



Length 11.7, diam. 5.8, length of apert. 5.5 mm. Kawailoa. 



76. L. SUCCINTA (Newcomb). PI. 5, figs. 90, 91. 



"Shell obesely conoid, thin, shining, corneous, longitudin- 

 ally striate; whorls 7, flatly convex, slightly rugose above, 

 not margined ; suture but slightly impressed ; aperture broadly 

 ovate; columella deeply excavated, short, terminating in a 

 broad plicate tooth; lip simple, slightly thickened within, 

 with or without a broad obsolete white or brown central band 

 on the last whorl, or a fine revolving sutural line of the 

 same 'Color. Length 12.5, diam. 7 mm." (Newc.)

 (Perkins).

A large obese species of the type of L. resinula Gul., 

 L. pyramis Pfr. and L. glutinosa Pfr. It is most nearly 

 related to the latter, from which it differs in size, slightly 

 blunter spire and slightly more striate surface. Newcomb 's 

 figure is not good. The specimens in Coll. Academy of 

 Natural Sciences, presented by the author, are labeled as a 

 variety. One of the shells has the following measurements: 

 length 12.6, diam. 7, alt. of ap. 6.3 mm.
