This species closely resembles P. Uneata of southern Europe, 

 with which a comparison will be required in order to point out the 

 essential differences. From the distance of locality there can, 

 however, be no identity of species. Inhabits San Diego Bay, 

 where I found them very numerous in December, crawlmg and 

 burrowing on the sandy flats. After the floods in January, none 

 were to be found. 



Doris monteret/ensis, n sp. 



jSj). ch. — Pale yello^vish with scattered black spots (or entirely

 tacles knob-shaped, branchial rays bipinnate, short, in eight divisions, 

 forming a crown-shaped expansion on the posterior third of the 

 dorsum. Foot expanded into a broad, thin margin, as wide as the 

 mantle. Length, 3 inches ; breadth, 1 inch ; height, | inch ; form 

 elongated oval. 



Dredged in six to ten fathoms, in Monterey Bay, adhering to 

 fragments of sandstone — only two obtained in September. Small 

 specimens, a^pparently the same species fomid in San Francisco 

 Bay by Dr. Frick.

 about the same. 



Found under stones in San Diego Bay. Rare. 



Doris {Asteronotus f) alabastrina, n. sp. 



Sp. ch. — Alabaster white, opaque, form depressed-oval dorsal 

 tentacles short, acute, branchiae of twelve simple rays expanding in 

 the posterior fifth of the body. Length, four tenths in., breadth,
