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 rnollusks, 

 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 sty Una 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 place 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 Shells " as P. lima refers to another 

 shell M. B. W.). 



NOTES AND NEWS. 



In L'Echange for June, 1897, p. 46, Mr. Locard establishes anew 

 genus Assiminopsis for the new A. abyssorum, from the Atlantic 

 south of Portugal in 1,205 metres depth. It is probably Rissoid.
