The most aberrant species of the genus. At first glance 

 it appears to be a Tornatettides, but the animals are ovi- 

 parous. This species is smaller and has fewer whorls than 

 any of the other species ; the whorls are more convex, and the 

 columellar folds are quite weak and diagonal. In young shells 

 the columellar folds are remarkably weak, but the parietal 

 lamella is proportionately stronger than in adults. The shell 

 is distinctly striate. The embryonic whorls are distinctly en- 

 circled with about 20 spiral striae. 



The shell is stouter in form and has a longer parietal lamella 

 than Tornatellides bellus or T. plagioptyx, species which other- 

 wise somewhat resemble T. baldwiniana. 



ADDITIONS AND CORRECTIONS. 



PAGE 44. 2d line under A. LINEOLATA (Newcomb). Read 

 lineolata card in place of lineolata cord. 



PAGE 73. Key to species of Oahu. In the third and fourth 

 lines the phrase whorls of the spire but slightly 

 convex was misplaced. It belongs in the following 

 paragraph following the guide-letter a. 



PAGE 121. Second paragraph from bottom. The Sunday 

 Island form is perhaps referable to typical E. 

 ovatum rather than to the variety apertum. 



PAGE 125. 7th line from bottom. For Tornatellina manilense 

 read Tornatellina manilensis. 



LEPTACHATINA. 



The following species probably belongs to this genus. It is 

 unknown to other authors, and as the type is lost, it may be 

 disregarded as unidentifiable. 



Bulimus pumicatus Mighels. Shell dextral, conical, polished, 

 glossy, light brown color, imperforate ; whorls 7, slightly con- 

 vex ; aperture oval, small, with a delicate fold on the left side ;
