which grows 2^ inches long. Like M. cretacea Gabb, which he calls 

 the oldest known of the genus, it is small and even simpler in form 

 than that species. Two only were found in Rose Canon by Mr. Fair- 

 banks. Cret. B. 



Stomatia intermedia n. sp. (PI. Ill, Fig. 43.) 



Shell haliotiform, whorls two or three, flattened, rapidly expanding, 

 with four strongly carinate ribs revolving above the margin and one or 

 two below it; the outer ones sometimes forming an undulating margin 

 toward the anterior end. Interspaces sub-equal, slightly concave, with 

 revolving ridges near apex, crossed by irregular radiating lines of growth. 

 The sculpture is sometimes scaly or imbricated. Apex distant from 

 margin, the outer whorl forming an expansion along the posterior margin, 

 equal to one sixth of the length of shell. Length, 1 inch or more; 

 breadth, 0.90; height, 0.35. One specimen, half grown, retains a reddish 

 color on the surface, and more perfect sculpture, looking like a Haliotis 

 rufescens, without the perforations. Only five specimens found, in Cret. 

 A, at the west base of Point Loma, San Diego. 



The figure is made from a combination of three specimens, as none 

 singly shows all the characters of the species. 



Resembles the S. suciensis Whiteaves, of the Vancouver I. group, and 

 is possibly a connecting link between that and var. carinata Wh., but 

 seems more likely to be quite distinct. 



Calliostoma kempiana n. sp. (PI. Ill, Figs. 33, 34.) 



Shell with a conical outline, higher than wide, imperforate; whorls 

 six or seven, flattened, with strong vertical ribs closely arranged. 

 Basal margin crenated by the ribs; the surface with about ten con- 

 centric riblets. (Mouth and columellar region concealed by the matrix.) 

 Height, 0.50; breadth of base, 0.44. 



Three specimens found at the west base of Pt. Loma, by Mr. Fair- 

 banks. This species seems quite different from C. radiata Gabb, which 

 was from still older beds. 



By request of Mr. Fairbanks, I have named this handsome species 

 in honor of his wife, formerly Miss Kemp, who has taken much interest 

 in fossils, and assisted him in scientific work. 



Tornatella normalis n. sp. (Pi. Ill, Figs. 36, 37.) 



Shell oliviform, whorls six, apical subacute; next four gradually 

 enlarging, with five to ten sharply-impressed grooves parallel with the 

 sutures, which are also rather deeply impressed; body- whorl with about 

 fifty similar grooves, crossed by irregular lines of growth, ending 

 anteriorly in an obtuse point. Mouth subovate, acute posteriorly; 

 columella with one basal plait. Length, 0.65 inch; breadth, 0.25; body- 

 whorl, 0.50 long.
