36 THE NAUTILUS. 



pi. 1-24, Feb., 1914). This part covers the non-marine species 

 and a portion of the marine Gasteropoda. The author's treat- 

 ment of Buccinuni and allied genera is very interesting. Of 

 B. undatum 12 varieties are recognized. To the form which 

 is also found on the eastern coast of North America the var- 

 ietal name of littoralis King (1846) is used. There is appar- 

 ently an older name for this form undulatum Moller 

 (Kroyer's Tidsskrift, vol. iv, p. 84, 1842) which was adopted 

 by Stimpson. Some sixteen other species of Buccinuni are 

 described and figured, including a number found living on the 

 Banks of Newfoundland. A new genus Searlesia is proposed 

 for the group of which Trophon costifera S. V. Wood is the 

 type. 1 The Chrysodomus dirus Eeeve =icmts Old. =sit- 

 kensis Midd. of the Pacific coast probably belongs to this 

 genus. Neptunea decemcostata Say is considered a variety of 

 N. despecta Linne. The author is very conservative, using 

 most of the older generic names, rather than those now adopted 

 by most conchologists. The work is indispensable to one 

 studying the boreal fauna, from the intimate relation of 

 British Pliocene with recent North Atlantic species. The 

 figures are excellent phototypes. C. W. J. 



LAND SHELLS FROM THE TERTIARY OF WYOMING. By T. D. 

 A. Cockerell. (Bull. Arner. Mus. Nat. Hist., vol. 33, pp. 323- 

 325.) Professor Cockerell's studies in tertiary insects and 

 land shells of the Rocky Mountain region are giving us 

 glimpses of a fauna of surpassing interest. His last paper 

 describes several types new to America. Protoboysia is a 

 Pupoid snail with the last whorl running up the spire nearly 

 to the summit ; length and width 31/2 mm. It differs from the 

 Indian Boysia by a peculiar construction of the last whorl. 

 Boysia sinclairi and B. phenacodorum are forms which ' ' can- 

 not at present be distinguished from Boysia." With these 

 species which certainly seem to have Oriental relations, were 

 found a Vitrea, a Thysanophora, Pyramidula ralstonensis and 

 Oreohelix megarche. All are from the Clark's Fork Basin.

'The species of Searlesia resembles Urosalpinx rather closely. It is re- 

 markable that so large a number (12) should be found in one restricted area.
