THE NAUTILUS. 81 
the Glycimeris, unless an expert, one is apt at the end of his search, 
to be very much disgusted at finding instead of the desired mollusks, 
nothing but a “sea cucumber.” 
At San Pedro I secured a dozen or more living specimens of 
Chrysodomus Kellettii, brought in from deep water by a fisherman, 
and, collected on the mud-flats a few Trophon Belcheri and a large 
Mactra Hemphillii. 
_ In the pholas bed at San Pedro I found some large specimens of 
Adula stylina and Lithophagus plumula, three young Parapholas 
Californica and a few specimens of Nettastomella Darwinii, a little 
borer about three-fourths of an inch long and gaping widely at the 
posterior end. 
After a heavy tide at Long Beach one may collect occasional 
specimens of Periploma planiuscula Sby., Clidiophora punctata and 
odd valves of Raeta undulata and Yoldia Cooperi. 
While on a camping trip this summer to Maliban Ranch, a 
rocky strip of sea coast about twenty miles north of Santa Monica, 
I collected my first specimens of Lasea rubra. It is a tiny bivalve 
about the size of a pin-head, and the smallest Pelecypod on this 
coast. I found them on the byssus of Mytilus Californicus. On 
the same rocks with, and feeding on the Mytilus I found a fine 
series of Purpura saxicola the largest and most beautiful I have 
seen. In color they varied from white and orange to jet black, 
some striped, some plain, others smooth, and still often slightly 
roughened. I think this is about the only piace in Los Angeles 
County where Purpuras are to be found. (Two or three collectors 
have found Purpuras at Portuguese Bend, in Los Angeles County. 
Purpura saxicola and Purpura lima var. emarginata, are syno- 
nymous terms used for one of our Californica purpuras. The 
shell figured in “ West Coast Sheils” as P. lima refers to another 
shell—M. B. W.). 
NOTES AND NEWS. 
In L’ Echange for June, 1897, p. 46, Mr. Locard establishes a new 
genus Assiminopsis for the new A. abyssorum, from the Atlantic 
south of Portugal in 1,205 metres depth. It is probably Rissoid.
