Cal. (T. S. Oldroyd), as follows: "Lateral areas with 4 (on one 

 side of valve ii, 5; on one side of valve iv and v, 3) radial riblets, 

 which are very weakly, hardly perceptibly, granose. Sutures very 

 feebly crenate. Anterior and posterior valves with 9 slits each. 

 Color reddish (but not at all of an orange cast), with a few in- 

 conspicuous white spots on some of the lateral areas.

1702 Ischnochiton scabricostata Cpr. 



Type locality: — Long Beach, Cal. (Miss Ida M. Shepard). 



"Similar to C. decoratus in sculpture of end valves and lateral 

 areas; but the central areas have no wide, smooth triangle at the 

 ridge, such as types of C. decoratus have (Man. Conch. 14: t 58 

 f 18); being somewhat irregularly pitted towards the beaks, and 

 with rows of pits on each side of a small oblong tract at the ridge; 

 most valves pitted also on the ridge anteriorly." — Pilsbry, Nau- 

 tilus 10:50.

 tinctly ribbed, the ribs filiform, 4 of them entering the parietal
