After the manuscript for this paper had been submitted for pub- 

 lication, a paper came to hand published by Dr. William J. Clench, 

 in the Proceedings of the New England Zoological Club, which 

 named two of the species herein described — Chondropoma beatensis 

 and Brachypodella utowanae. 



CHONDROPOMA (CHONDROPOMIUM) WETMOREI, new sp«cies 



Plate 1. Figubes 8. 10 



Shell small, elongate-conic, semitranslucent, flesh-colored, with 

 four interrupted series of brown spots, which are arranged both in 

 axial and spiral order. The spaces that separate these brown spots 

 axially are about equal to the length of the spots, while the spaces 

 that separate them spirally are more than twice the width of the 

 spots. The early whorls are exceedingly thin, permitting the colu- 

 mella to be seen within. They are strongly rounded and marked by 

 retractively slanting incremental lines only. The succeeding turns 

 are also thin, but less so than the early whorls, and on these the 

 incremental lines become strengthened : there are also obsolete spiral 

 threads present, which give to the general surface a slightly mal- 

 leated appearance. The suture is well constricted ; the periphery of 

 the last whorl is well rounded. The base is short and strongly 

 rounded, narrowly umbilicated, and marked by the continuation of 

 the axial lines which here assume almost the strength of riblets and 

 a spiral thread marking the outer extremity of the umbilicus. Aper- 

 ture oval ; peristome simple and thin, not expanded. 



Type.— The type, U.S.N.M. No. 403886, has 4 whorls remaining, 

 and measures : Height, 9.7 mm ; diameter, 4.3 mm. 



Re7narks. — The nuclear whorls were described from a young 

 specimen having a little more than 5 whorls, of which the last shows 

 the spotting described in the type, the preceding ones being bluish 

 white. I have figured both specimens. 



Chrondropomella, new subgenus 



Shell broadly ovate, with the postnuclear whorls inflated, well 

 rounded, narrowly tabulated at the shoulder and marked by numer- 

 ous slightly retractively slanting, closely spaced, axial riblets. The 

 summit of the whorls is rendered feebly crenulated by the axial rib- 

 lets. Periphery well rounded. Base inflated, well rounded, openly 

 umbilicated, marked by the continuation of the axial riblets and 

 feebly developed spiral cords between the periphery and the edge of 

 the umbilicus. The umbilical wall is marked by stronger spiral 

 cords. Aperture large, with a broadly expanded flaring peristome 

 all around except at the parietal wall. The peristome not all in one
