96 THE NAUTILUS. 



California!! region, and had the good fortune to be able to inspect 

 nearly all the collections in private or public hands, which were of 

 importance for my studies. I propose from lime to time to give the 

 readers of the NAUTILUS the benefit of some of iny notes made dur- 

 ing the past summer. 



One of the most esthetically attractive collections on the coast, 

 containing large series of many of the rarer Calfcrnian marine shells, 

 is that of Dr. R. H. Tremper at Ontario, Cal. These .specimens are 

 mostly from southern California, and comprise besides rnolluscaa tine 

 series of the beautifully colored brachiopods ot the region, l.ciqueus 

 califomicus, the attractive crimson-tinted variety (i-ubescens) of' 

 Tcrebralula traiisversa, the white. Terebratulind kiiensis (also known 

 from Japan) and the gorgeous vermilion-streaked Tertbrululu obso- 

 leta. Attached by their peduncles to a rock brought up on a fisher- 

 man's hook from GO fathoms oft" Redondo were the first and last 

 mentioned species, wiili another which I did not recognize as Cali- 

 fornian, and which proved on comparison to be the Japanese Tere- 

 bratulina crossei Davidson, now for the first time reported from the 

 eastern border of the north Pacific. Another shell which seemed 

 particularly attractive, and which was new to me, was a variety of 

 Lottia gigantea, which may be called albomaculata, offering, instead 

 of the usual brown and grey upper surface, the feature of being 

 spotted with rounded white maculations regularly disposed. A pretty 

 variety (called by Mr. Hemphill var. Tremperi) of the fine purple- 

 brown Murex carpenteri Dall is decorated wilh two neat white bands 

 below the periphery. This was obtained by Dr. Tremper in 35 

 fathoms , off Newport, with many of the typical form. 



This collection contains, among other things, a most brilliant 

 series of the Pecten hastfitiis Sowerby in a great number of colo'r 

 varieties and fully the size of the northern P. Itericeus Gould. On 

 some of these, near the byssal notch, were seated examples of Copu- 

 las calijornicus, now for the first time reported as commensal with 

 any species except P. dieyensis. 



I may add to this note that through the intervention of a friend I 

 was able to purchase at Venice a specimen of ffa/iotis cracherodii, 

 which is believed by west coast collectors to be unique. It is a per- 

 fectly normal, moderate-sized specimen, probably obtained on the 

 coast of Los Angeles county, rather more elevated than the average, 

 and which has not been cleaned or modified in any way. Its pecu- 

 liarity consists in the fact that it has never possessed the slightest 

 trace of a perforation, even in the youngest stages, and there is not 

 even a suspicion of a notch at the margin. Other specimens like 

 Hemphill's remarkable variety hohneri have been seen with very few 

 perforations (Stearns records one with only two holes and a notch), 

 but these had earlier perforations which had been closed up and were 

 more or less abnormal in other respects. The present specimen 

 differs from all of them, in never having had any holes whatever.
