the disc; a lateral spine on either side and a terminal append^ 

 age short and truncate behind ; parallel to the lateral spijies is 

 a carina ; on the disc of the other side are five longitudinally 

 situated carinae : aperture sharply truncate on dorsum, but 

 strongly rounded on the opposite plate ; the slit reaching 

 quite to the lateral spines. 



Dimensions : Longitude 8 mm., latitude 7 mm. 



Geology: Pleistocene of Santa Monica Kange, Cal. 



Eulima raymondi n. sp. 



Form : Very attenuate : shell in texture as usual in this 

 genus smooth, glossy, and white in color; whorls eleven; 

 sutures scarcely impressed: strongly oblique: the three last 

 whorls equal to the remainder: aperture 2.2 mm. long and 

 1 mm. wide. Longitude 11 mm., latitude 2 mm. 



Not known to be living. 



Geology : Pleistocene Santa Monica Range, Cal. 



This cannot be confounded with any of the described spec- 

 ies belonging to this coast it being much more attenuated in 

 form comparing length with width, the mouth more pro- 

 duced forward and elongated and narrowed behind. Eleven 

 specimens have been secured and are true to form and pro- 

 portions. 



Chrysodomus amoldi n. sp. 



Shell thick, robust, chalk white : elegantly, fusiform : 

 spire about one-fifth of the whole : spire compressed : whorls 

 about five : nucleus and following whorl missing : the third 

 and fourth whorls are sculptured with rather wide transverse 

 ridges : but the fifth whorl the ridges are nearly obsolete ; 

 sutures roughly encrusted: body whorl strongly shouldered 

 but not tabled : the sculpture consists of five woolving, flat- 

 tened strive or ridges crossed at intervals by strong incre- 

 mental lines which perhaps in an unworn example might show 

 varices: in the fossil there appears faintly a cancellate pat- 

 tern : all the whorls bear an alternate series of fine revolving 

 ridges which on the body Avhorl gages two to a mm. ; colum- 

 nella medium, twisted : channel open but shallow : incrusted 

 thickly interiverity : aperture pyrif orm umbilicus subperf orate 

 as in Pisania fortis Carpt. 



Dimensions: Long 40 mm.: lat. 20 mm. 



Geological formation. Pliocene. One specimen. 



Locality: Crawfish Gorge's: San Pedro, Cal. 



Chrysodomus merriami n. sp. 



Shell bucciniform : whorls eight : nucleus eroded : incre- 

 mental and fine lines appear as soon as growth begins which 

 increase in regular ratio until the body whorl show ridges 

 and appressed lines that gage six to a mm. Apex not de-
