Macroceramus Kieneii, Pfr. 



Dr. Pl'eiffer described Macro ceramus Kieneri as a Buliimis, 

 in Proc. Zool. Soc, 1846, and later, in Mon. Hel. Viv., II, 79, 

 1848, as follows : 



T. breviter rimata, cylindraceo-turrita, tennis, oblique confertim costata, 

 fusco-corneo et albido irregulariter marinorata ; spira turrita, apice acu- 

 tiusculo nigricans ; sutura profunda, crenata ; anfr. 13 convexi, ultimus \ 

 longitudinis subiequans, basi obsolete unicarinatus ; apertura lunato-circu- 

 laris ; perist. simplex, undique expausum, marginibus conniventibus, dextro 

 valde arcuato, columellari dilatato, patente. 



Long. 18, diam. anfr. antepenult. 6 mill. Ap. 4S mill, longa, 4J lata. 

 Habitat in Honduras. 



In the Proc. Boston Soc. N. H., Ill, 1848, Dr. Gould de- 

 scribed Pupa pontifica, and the following description is given 

 of the species, as Gylindrella pontifica, in Terr. Moll., II, 306, 

 Plate LXIX, fig. 1. 



Shell fusiform, attenuated-cylindrical, whitish, or grayish clouded and 

 marbled with brown ; spire acuminate ; whorls from 9 to 12, rounded, 

 with numerous oblique, prominent striae, or ribs ; suture impressed, crenu- 

 lated by the extension of the alternate ribs across it ; aperture rounded, ob- 

 lique ; lip thin, somewhat reflected ; axis impressed, not truly perforate. 

 On the last whorl, a colored line revolves : this is sometimes raised a little 

 from the surface, and sometimes is shai'p like a delicate carina.
