New Land Mollusks from Madagascar and Mexico

The material described in this paper was sent to me by Mr. Allyn G. Smith of the California Academy of Natural Sciences. As the shells were collected in areas outside of the scope of said institution, Chicago Natural History Museum was kindly allowed to keep the unique specimens, the types of two of the three species described herein; there are several paratypes of the third, and some of these will be returned to the Academy of Natural Sciences.

Malarinia, new genus

An apparently new genus of Cyclophoracea, looking somewhat like a slender Cochlostoma of the subgenus Turritus. The only known species, which thus automatically becomes the type species, will be described below under the name of Malarinia hova. In this description, additional characters of the genus Malarinia will be mentioned.

Diagnosis.—A rather small cyclophoraceous shell, slender, with ventricose whorls which are densely costulate, and with an aperture measuring about one fourth of the entire height.
