12 THE NAUTILUS. 



The entire set was donated to the Acad. Nat. Sci. of Philadelphia. 

 C. exile and P. c. anthonyi were the most abundant forms in the col- 

 lection, and E. sterkii is, I believe, new to the State. E. G.

NOTK ON CmciNARiA c^ELATA MAZYCK. In the Catalogue of 

 American Land Shells published in NAUTILUS XI. (p. 128), this 

 form was subordinated lo C. duranti, as a sub-species. By the cour- 

 tesy of Mr. Mazyck, I have been able to examine the type specimen 

 of c&lata. On going over the series in the collection of the Acad- 

 emy, no specimens were found connecting it with duranti, and I now 

 believe it to be a distinct and well-characterized species, one of the 

 handsomest of the genus. H. A. PILSDRY. 



MR. A. A. HINKLEY made a brief mid-winter journey to Guate- 

 mala, obtaining some interesting additions to his former collections 

 there. A fine series of the large Pachycheiti of Lake Ysabel and 

 environs was taken. Among the land shells he secured a good series 

 of the splendid Ccdocentrum gigcts \. Mart. II. A. P.

A PRELIMINARY LIST OF THE MOLLUSC A OF MISSOURI (ex- 

 clusive of the Unionida). By F. A. SAMPSON. Trans, of the 

 Academy of Science of St. Louis, xxii, July 18, 1913. The various 

 State catalogues which have been brought out in the last ten or fifteen 

 years have recorded data of great value to the student of distribution 

 of mollusks, indispensable to inquiries into the origin and migrations 

 of the several groups of our fauna. Missouri is an especially inter- 

 esting state. Lying near the western border of the humid area, 

 the northern border of the Ozarkian fauna, and within the peri- 

 pheral range of some Austral forms, it is an area where numerous 

 species reach their extreme range. Mr. Sampson has given in this 

 catalogue the results of many years of work in the state, a total of 

 117 species and varieties, and some 900 locality records. Among 

 the species first described from Missouri we note two not in Mr. 

 Sampson's list : Polygyra blandiana Pils. and Ferr. and Amnicola 

 missouriensis Pils. H. A. P.
