Of No. 8, two odd valves, and of No. 9, a single perfect specimen on sand- 

 spit; 15, an odd valve, one perfect specimen found by Col. Jewett, who ac- 

 companied me ; 49, one specimen ; (I am informed by the residents of the town 

 that this species is abundant at a point about ten miles up the coast) ; 50 and 

 51, very common (young specimens frequently and mature shells sometimes 

 umbilicated) ; 68, frequent ; a well-marked species ; (often confounded with the 

 young shells of 67; the young shells of 67 are sometimes adorned with zigzag 

 brown markings upon alight ground, otherwise, uo resemblance between them ; 

 68 is in shape between 67 and O. batica, of Carpenter) ; 71 is but an extreme 

 form of 70, as I am convinced by an examination of not less than one thou- 

 sand specimens, received by me from Monterey ; 72 — if " gausapata " and 

 " Californiana" belong to "Amycla," this certainly should be placed with them ; 

 76, particularly abundant (some 2000 living specimens collected ; June 23d, 

 this species had just commenced depositing their pink-tinted eggs, a few of which 

 were obtained) ; 83, the immature shells of this species closely resemble some 

 specimens of 78. 



Professor Whitney exhibited a portion of a human skull recently 

 deposited at the office of the State Geological Survey, by Dr. 

 Thomas Jones, of Murphy's Camp, Calaveras County. He read 

 the following : 



Species marked with a * one specimen ; thus t two specimens ; of the remainder from 

 three specimens upwards were collected.
