with multitudinous, nanow, spiral bands of the same; 

 whorls 5j somewhat flattened, regularly increasing, sculptured 

 with radiate, transverse strife and extremely fine and closely- 

 set, rather wavy, microscopic, spiral strife ; suture impressed ; 

 base of shell not very convex, sculptured as on the spire ; 

 umbilicus wide ; columella margin obliquely descending, 

 curved below, diffused above into a restricted, well-defined, 

 whitish, parietal callus which reaches to the upper margin of

 projecting in front ; aperture broadly and rather compressedly 

 and obliquely sublunate.

Animonoceras rosenbergiana, sp. n. 



Shell allied to A. pucai/aensis, Preston, but of a pale 

 3"ellowish-olive tint, with no trace of spiral colour-bands, the 

 spire is rather more exserted, and, while the spiral stripe are 

 even finer, the transverse stride are much more pronounced; 

 the suture is narrowly margined below, which is not the case 

 in A. pucagaensts, the last whorl descends somewhat, tiie 

 umbilicus is much narrower, and the parietal callus is of a 

 reddish hue.

Bulimulus apicepunctata, sp. n. 



Shell fusiform, reddish brown, variegated with oblique,

 round the umbilicus, umbilicus somewhat broad, deep ; 

 columella margin vertically descending in a slight curve, 

 thin, broadly outwardly expanded, clitfiised above into a 

 light, well-defined, parietal callus, which enters the shelljust 

 behind tlie upper margin of the labrum ; labrum whitish,

 the aperture above ; aperture rather elongately ovate.
