48 AMERICAN JOURNAL 



Pinos, finding three additions. At the point the light-house 

 keeper showed me Lucapina crenulata, saying that it was only 

 found alive at spring tides. 



Summary and Additions. 



The whole number obtained thus consisted of one hundred and 

 twenty-six first found on shore, and eighty first obtained by 

 dredging, (including nine which are scarcely more than varieties 

 of others). I also obtained twenty of the dredged species after- 

 wards on shore, and all but twelve of them have since been found 

 above tides by myself or others, usually, however, dead and im- 

 perfect. 



Many, on the other hand, which I dredged only dead, have 

 since been found by Dall, Stearns, Newcomb and Canfield living 

 among the granite rocks at extreme spring tides, low water, in 

 midsummer or winter. Harford has found others by wading in 

 below tides, and carrying large stones ashore with the animals 

 adhering to them. In such places dredging is impossible. These 

 gentlemen have also added largely to the list of Monterey shells, 

 which now number about ol6 species. Had I wished merely to 

 make a local list when collecting there, I might have increased 

 it much by preserving many species which I found only in a 

 fragmentary state, and thought not worth preserving, as I knew 

 they could be obtained better elsewhere. I can even now recall 

 to memory many such observed on the beach, but do not include 

 them. 



Although imperfect as a local list, the number is remarkable 

 compared with what I found at Santa Cruz during a year's resi- 

 dence some years later, when I visited the beach often and 

 during almost every monthly low tide. I got there thirty-eight 

 marine Acephala, seventy-nine Gasteropoda, ten terrestrial, two 

 fresh Avater Acephala, five Gasteropoda, total 134 only. 



And small as the number is, it includes fifty species not in my 

 Monterey list, (which, however, are mostly found there,) and I 

 have therefore given them with the former locality, as it is situ- 

 ated on the same bay only twenty-five miles north of Monterey. 



In the " Geographical Catalogue " I included the additions 

 made previous to 1867 by the gentlemen above mentioned, and 

 in my manuscript report have tabulated their contributions more 

 fully. Since that date, however, twenty or more new species 

 have been discovered or determined by them and Carpenter, 

 which are not yet published. It would be therefore improper 

 for me even to give their manuscript names, as they will doubt- 

 less be all published in due time. Six are Chitonidse, three 

 Patelloid, the rest mostly minute.
