THE NAUTILUS. 39 



Venericardia ventricosa Gld. Abundant. 



Pecten jordani Arnold. Fragments and two juv. 



Pecten caurinus Gld. Fragments. 



Pecten (sp.). Fragments. 



Pecten hastatus Sby. Several valves. 



*Monia macroschisma Desh. One valve. 



*Glycymeris barbarensis Conr. One valve. 



Strongylocentrotus purpuratus Stimp. Fragments of the test and 

 loose spines of this sea-urchin. 



*Platidea anomioides Scacch. One perfect shell probably refer- 

 able to this species was found which agrees well with specimens 

 from San Pedro Bay (200 fathoms), except that the foramen is 

 relatively smaller and the posterior and anterior angles are more 



acute.

In the Proceedings of the U. S. National Museum, Vol. XXX, 

 Messrs. Dall and Bartsch propose the specific name moiitereyensis for 

 the preoccupied Turbom'Ila gracillima of Gabb. The authors must 

 have overlooked the fact that Dr. Cooper in his Monterey list pub- 

 lished in the American Journal of Conchology for 1870 likewise 

 noticed the untenability of Gabb's name and rechristened the species 

 Chemnitzia gabbiana, so that this name having priority must stand 



as Turbonilla (^Chemnitzia?) gabbiana (J. G. C).

Nassa perpinguis, var. bifasciata, nov. Among the moUusca col- 

 lected recently at San Pedro by various collectors has been a color 

 form of Nassa perpinguis Hds., which is strikingly distinct and is 

 certainly worthy of a varietal name if color forms must be named. 

 It differs from the ordinary form in the presence of two broad spiral 

 bands of a deep chestnut color in abrupt contrast to the grayish-buff 

 ground color of the shell. One of these bands is situated just below 

 the suture, one about the periphery, and occasionally a fainter band 

 makes it appearance at the extreme base of the last whorl. The 

 bands vary considerably in width, but as yet I have seen no speci- 

 mens having but a single band. 



Additional Notes on Monterey Mollusks. 

 In my paper on the Molluscan Fauna of Monterey Bay, California, 

 which appeared in the numbers of this magazine running from June 

 to September, 1907, there were a few unavoidable errors and omis-
