Lower Shales, Division B, at Biviwii's Rivei*, Y. I. (^one) ; Productive 

 Coal Measures, Division A., at the Nanaimo Eivor, ten miles up, (one) ; 

 ami Elunden Point, V. I. (two) ; also at the Sucia Islands, eight oi- ten 

 specimens; J. Richardson, 1871-74. 



This shell, which occurs at many localities in the Vancouver Cretaceous, 

 is believed to be a small form of the European Natica excavata. Mr. Tryon, 

 who has kindh^ compared two of the best specimens collected by Mr. 

 Richardson with Mr. Gabb's types of Nntka in'racnrinatd from New 

 Jersey anil GijDdes ^piUinini.i from M ississij^pi in the Museum of the 

 Academy of Natural Sciences of Philadelphia, agrees with the writer iu 

 referring all three to y. excavata. G-yrodes Conradlanoo'LQ-Ahh,^ from the 

 Chico Group of Califoi-nia, is also probably another variety of the present 

 species, in which the truncation of the upper part of the whorl is obsolete. 

 The characters given above, though generallj' applicable, are subject to 

 some variation, for in a specimen of G. excavata^ from Browu's River, 

 V. I., the whorls appear to be evenly rounded, or nearly so, above, and 

 the umbilical keel is barely perceptible.

Sycodes eypj^ceoides of Gabb is almost unquestionably the same shell as 

 the Pyrula glabra of Shumard, and the latter specific name must be 

 retained as having priority of date.
