Chrysodomus imperialis Dall. 



Neptunea maxfieldi Reagan, p. 219, pi. 6, fig. 54, 1909. 



This has been well figured both in Professional Paper 59, and 

 by Arnold in U. S. Geological Survey Bulletin 398. 



Liomesus f sulculatus Dall. 



Monoceros engonatum (Conrad) Reagan, p. 220, pi. 6, fig. 55, 

 1909. 

 The specimens are too imperfect basally to be certain that they 

 belong to Liomesus. The Trophon species cited on page 220, is 

 not among the specimens received. 



Nucella sp. 



Purpura crispata (Chemnitz) Reagan, p. 121, pi. 6, fig. 57, 1909. 



This is hardly identifiable, owing to its defective condition, but 

 is probably a Nucella allied to M. lamellosa Gmellin. 



The specimen identified by Reagan as Purpura lapillus is not 

 in the collection, but was certainly not the Atlantic species. 



Nucella ( ? var.) quillayutea Reagan. 



Purpura lapillus var. quillayutea Reagan, p. 221, pi. 6, figs. 

 57 a-o., 1909. 

 This is closely related to Nucella lamellosa, but is sufficiently 

 distinct from any of the recent forms to constitute a good variety 

 if not a species. 



Strombiformis washingtoni Reagan. 



Eulima washingtoni Reagan, p. 223, pi. 6, fig. 60, 1909. 

 Eulima smithi Reagan, 1. c, fig. 61, 1909. 



This is a good and rather remarkable species of Melanelloid 

 type. The aperture not being accessible, the genus is not posi- 

 tively determined, but the shell resembles Strombiformis riversi 

 Bartsch, from the Pliocene of Santa Monica. 



The difference noted by Reagan between his two species is due 

 to the fact that one specimen is decorticated. 



Gyrineum mediocre Dall. 



Ranella marshalli Reagan, p. 222, pi. 6, fig. 62, 1909. 



The type specimen is identical with that from Coos Bay. 



Natica (Cryptonatica) consors Dall. 



Natica (Cryptonatica) clausa (Broderip) Reagan, p. 224, pi. 6, 

 fig. 63, 1909. 

 This is the smaller common Natica of these beds.
