to all West Coast conchologists, and appears to flourish most abundantly from 

 Sitka to Oregon. It is sufficiently distinct from any other Califoruian species 

 to require no special care in making comparisons. The Puget Sound speci- 

 raeas have a tendency to a greenish-gray hue, with bright orange mouth, less 

 conspicuous grooving and more solid shell than others. Those from further 

 north are usuallj' of a dark lurid brown, within and without; the revolving 

 threads more even, and the grooves wider. This species seems particularly 

 liable to individual abnormalities or deformities, and has the external aspect, 

 as remarked by Gould, of a Euthria.

The name of Fusus amhustus has been very widely quoted for one or two 

 Califoruian species hereafter to be mentioned, but there is no reason for be- 

 lieving that it exists in California at all. Dr. Gould's figure excellently rep- 

 resents the fresh condition of living specimens, though fresh specimens are 

 often lighter. The two nuclear whorls are thin, dark brown, and polished, 

 having the texture glassy rather than porcellanous. 



The fact that Dr. Gould's figure is totally unlike any of the Californiau 

 species renders it a matter of surprise that it should have been sought to apply 

 it to any of them; however, this has been persistently and erroneously done. 



From a photograph of an original drawing made by the author from his 

 type in the British Museum, it becomes possible to identify his minute and 

 very young shell with that of Dr. Gould. It would have been as well, on 

 some accounts, to have avoided applying names to such material, which, 

 unless the specimens can be consulted, is only too apt to form a stumbling 

 block in the way of identification of mature and perfect specimens. The 

 other species (?) F. apertus, described at the same time from an even less 

 perfect specimen, is hardly likely to be identified. 



This species is, of course, only included here to assist in'cleariug up the 

 synonymy.

Habitat, Mendocino Co., Cal., Harford; Farallones, Watkins. 



This is an excellent species, but very rare. The reception from Dr. Car- 

 penter of a specimen obtained by him from Mr. Stearns, has enabled me to 

 identify a young specimen in my own collection received from Mr. Watkins, 

 and collected by him on the Farallones. This is the more fortunate, as the 

 original type has not been accessible for some years. As the original diag- 

 nosis is brief, a few additional remarks may be useful.
