REMARKS. 



269. Leptothyra sanguinea, Carp. Common at Monterey ; all shades of 



color from light red to very dark purple ; sometimes broadly banded 



with white ; another variety is marked with irregular whitish streaks, 



causing a resemblance to the young shells of 282, Omphal ius fuscescens. 



275. Troclnsms Norrisii, Sby. The apex whorls of the young shells have 



a spiral liand tesselated with white and red. 

 388. Comis Californicus, Hds. When young, the shells of this species are 

 ornamented with yellowish brown markings upon a light bluish ground. 



A Surcula Carpenteriana, Gabb. The most perfect recent specimen of 

 this rare species that I have seen (described by Mr. Gabb in Vol. Ill, 

 Cal. Acad. Pro. p. 183) was obtained by Mr. Hepburn ; when perfect, 

 one of the finest shells of the upper Califoruian province ; the specimen 

 referred to is of a clear light salmon color, traversed spirally by narrow 

 bands or broad lines of reddish brown, and resembling in its general 

 coloring that equally fine shell Narona Cooperi, Gabb, described as 

 above, p. 186. 

 460ri. Purpura var. ostrina, Gld. Deposits its yellowish eggs on the rocks 

 at Black Point and the Cliff House near San Fraucisco, in the latter 

 part of June (1865) and the middle of July (1866). 



75. Pachydesma crassatelloides, Conr. Valves frequently marked with 

 broad radiating bands of light brown. 

 266. Pomaulax undosus, Wood. Young shells approach closely to the 



immature form of Pachypoma gibberosum, Chemn. 

 281. Mr. Carpenter remarks in his supplementary Report to the B. A., in 

 connection with Chlorostoma aureotinctum, Fbs. : " mouth orange 

 spotted." I should amend this so as to read umbilicus stained with 

 orange. 

 456. Ampkissa corrugata, Rve. This species assumes nearly every shade 

 of color and an innumerable variety of markings ; the latter being 

 generally some shade of brown upon a lighter colored ground. 



74. Amiantis callosa, Conr. An aberrant form of this species in my col- 

 lection suggests, in outline, Dosinia. 



88. Saxidomus aratus, Gld. A single specimen of a young shell of this 

 species (Coll. Stearns) is prettily marked with brown upou the pos- 

 terior dorsal portion of the valves.
