From an examination of Lea's original specimen of 

 Lecontii, as well as from his description and figure, I am 

 convinced of its identity with loricata. Gould expresses 

 this opinion (Ex. Ex. p.* 501, Addenda), Pfeiffer copies 

 Lea's description, not having seen the shell, and remarks 

 " Nonne varietas umbilicata H. pustulce ? ' 



" Animal white, linear, rough, posteriorly acute, tentacles 

 very short." (Thomson.) 



The shell is furnished with the peculiar internal fulcrum 

 mentioned by Lea, (1. c.)

All the more recent writers agree in placing H. Nuttalli- 

 ana in the synonymy of H. fidelis, excepting Gould, who, 

 as late as 1852, (1. c.) remarks, " As there are other species 

 in that region corresponding equally well with Gray's 

 indefinite description, I think it proper to retain Mr. Lea's 

 name until the identity can be fully settled." 



* On the copy of the plate referred to, engraved by Delarue, the aperture of 

 Helix maxillata is erroneously placed next the figure of this species. This mis- 

 take does not occur on the other copy of the plate.
