AENOLD — THE PALEONTOLOGY AND STRATIGRAPHY OF SAN PEDRO. 325 



Shell conoidal, thick; whorls six, slightly convex; slight shoulder posteriorly near suture; 

 ornamentation consists of numerous prominent, fine, oblique, incremental lines; suture impressed, 

 distinct; umbilicus obsolete; base flat; obsolete spiral ornamentation; outer lip thin, effuse. 



DimensioHS. — Long. 28 mm.; lat. 28 mm.; defl. 65 degrees. 



Distinguishable from C. montereyi, which il resembles in shape, by more 

 convex whorls, obsolete umbilicus and lack of spiral ornamentation. 



This species is rare in the Pliocene of Deadman Island, and in the upper 

 San Pedro series of Deadman Island and Crawfish George's. 



Living. — Cape Mendocino to San Diego (Cooper): Japan ? (Tryon). 



Fleistocp.ne. — Santa Barbara Island (Cooper): San Pedro (Arnold). 



Pliocene. — San Pedro (Arnold).

Trochus funebralis A. Ad., Fischer, Coq. Viv., p. 173, PI. LVII, fig. 3. 



Shell conoidal, thick, black; whorls five, only slightly convex; ornamentation of eight spiral 

 ridges crossed by fine, oblique liruke of growth; suture di.stinct; base flat; ornamentation same as 

 whorls, with the oblique incremental lines brought into prominence, as a rule; umbilicus obsolete; 

 outer lip effuse, with one prominent and one smaller tubercle near umbilical region; inner lip 

 incrusted. 



Dimensions. — Long. iS mm.; lat. 19 mm.; defl. 74 degrees. 



Distinguishable by black color, spiral ridges and obsolete umbilicus. 



Rare in the lower San Pedro series of Deadman Island and San Pedro; and 

 in upper San Pedro series of Deadman Island, San Pedro, Los Cerritos, Long Beach, 

 and Crawfish George's. Found also in the Pleistocene at Barlow's ranch, Ventura; 

 and at Pacific Beach, San Diego. 



Living. — Sitka to San Diego (Cooper). 



Pleistocene. — Santa Barbara to San Diego (Cooper): San Pedro; Ventura; 

 San Diego (Arnold). 



374. Chlorostoma funebrale A. Adavis, var. subapertum Carpenter.

 Nat. Mus., Vol. XV, 1892, p. 200, PI. XXI, fig. 6. 



Shell resembles G. funebrale, but differs in having more prominent spiral 

 ridges, which are usually much more rugose, and in having a prominent umbilical pit. 

 Found in same localities as C. funebrale. 



Living. — Vancouver district (Carpenter) : West Coast. 



Pleistocene. — San Pedro (Arnold).
