266 Doris (Archidoris) montereyensis (Cooper) Bergh 

 Cooper, Cal ac pr 2:204. 



Pale yellowish with scattered black spots (or entirely brown?), 

 mantle rough tuberculate, or nearly smooth, dorsal tentacles 

 knob-shaped, branchial rays bipinnate, short, in 8 divisions, form- 

 ing a crown-shaped expansion on the posterior third of the dor- 

 sum. Foot expanded into broad, thin margin, as wide as the 

 mantle. Length 3, breadth 1, height % inch; form elongated 

 oval. Dredged in 6-10 fathoms, in Monterey bay, California, ad- 

 hering to fragments of sandstone. Dr. Frick found small speci- 

 mens, apparently the same, in San Francisco bay, California. 



Santa Barbara at low water, larger in size and deeper color; 

 tentacles club-shaped, the branchial 7-8-parted, bipinnate and 

 from one opening. 



Orcutt, No. 19 (young fide Dall), from San Diego, appears de- 

 scribed among my notes as follows: — animal translucent white, 

 an inch or less long, the back of mantle liberally sprinkled with 

 irregular dots and blotches of brownish black which are most 

 conspicuous just behind the tentacles, near the center of the back, 

 and just forward of the branchiae. 



267 Doris alabastrina Cooper Cal ac pr 2:204 

 §Asteronotus? "Alabaster white, opaque, form depressed- 

 oval; dorsal tentacles short, acute, branchiae of 12 simple rays 

 expanding in the posterior fifth of the body. Length 4-tenths, 

 breadth 3-tenths inch. Under stones, San Diego bay, only one 

 found." 



268 Doris albopunctata Cooper Cal acpr3:58 (1863) 



"Form ovate, pointed behind, flattened, surface shining, mi- 

 nutely rugose. Tentacles club-shaped, retractile, branchial plume 

 6-8-parted, bipinnately divided, situated near the posterior ex- 

 tremity. Color yellow or orange brown, dorsal surface thinly 

 speckled with small white dots, each forming a slightly raised 

 papilla. Beneath paler. Length about 1, breadth one-third inch. 

 Dredged from a rocky bottom in 20 fathoms a mile from the shore 

 at Santa Barbara. Also found on rocks at low water mark near 

 the N. W. end of Catalina Island. Bolinas bay. 



Orcutt No. 25, San Diego. 



269 Doris (Diaulula) sandiegensis (Cp) Bergh 

 J. G. Cooper, Cal ac pr 2:204. 



Pale brownish yellow, with large annular brown spots irreg- 

 ularly scattered, varying from 10-20, or entirely brown. Surface 

 slightly rough, sometimes a little tuberculate. Dorsal tentacles 

 conical, retractile; branchiae large, rising in 5 parts which become 

 tripinnately divided, expanding so as to cover the posterior one- 

 third of the body like an umbrella. Mouth proboscidiform, with 

 2 short lateral tentacles. Length 3 % , breadth 2 y 2 , height Y 2 

 inch. Numerous among sea-grass on mud flats in San Diego bay, 

 Cal., from November to May. 



Among my notes I find: — "animal dirty white, % inch long; 

 mantle with 5-10 or more circles of dark brown irregularly placed 

 along the edge of the thick mantle." — Orcutt, number 23, from 

 San Diego, identified by Dall as this species. 



Cooper doubtfully placed in the section Actinocyclus, and has 

 reported 2 specimens from Santa Barbara, with tentacles conical, 

 acute, and states that the branchial orifice does not agree with the 

 "peculiar characters of Actironotus." Bolinas bay.
