Couth., E. Ei. Moll. p. 471, in absence of lateral membrane, size of mouth and 
cupules, and general coloration.” 
171. Onychoteuthis fusiformis, Gabb. “Cape Horn,” Mus. Ac. [San Clemente 
Is., Cal., Cooper, MS. ] 
From the ‘ Proc. Cal. Ac. N. 8.,’ 1863, p. 11, it appears that at least one 
molluse, a Teredo or Xylotrya, has already established for itself an economic 
celebrity. Piles have been entirely destroyed in six months from the time 
they were placed in the water. 
On March 2, 1863, Mr. Auguste Remond published, in the same Journal, 
English “ Descriptions of two new Species of Bivalves from the Tertiaries of 
Contra Costa County: ”— 
13. Cardium Gabbii, Rem. Late tert. deposit near Kirker’s Pass, in shelly sand, 
with Tapes regularis, Gabb, and Murex ponderosus, Gabb, both extinct. 
“ Basily recognized by heavy hinge and enormous laterals; lunule cari- 
nated.” [? Lrocardium. | 
Ostrea Bourgeoisii, Rem. Same locality. 
On April 20, 1863, Dr. Cooper described (in English) the following mol- 
luse, of which the only species previously known is from Cuba :— 
” 
21. Gundlachia Californica, Rowell. Fig. 5 (three views). Fifty specimens on 
water-plants in clear, stagnant ponds, at Marysville, Feather River, Rowell. 
On January 8, 1864, Dr. Newcomb described (in Latin) the following, 
with other Pulmonates from the State Survey, already tabulated in p. 609 :— 
115. Helix Hillebrandi, Newe. Tuolumne Co., Cal. One recent and several fossi 
shells, M. Voy. Like H. Thowarsi, but depressed and hirsute. 
The latest contribution to the malacology of California is one of the most 
interesting. It is described (in Latin) by Dr. Newcomb, Feb. 1, 1864 :— 
121. Pedicularia Californica, Newe. One specimen from coral growing on a mon- 
ster Echidnocerus, very deep water, Farallones Is., D. N. Robinson. “ As 
beautiful as P. elegantissima, Desh., from Is. Bourbon.” [ Mr. Pease also ob- 
tained a deep-water Pedicularia from coral in the Pacific Is., which Mr. 
Cuming affiliated to the Mediterranean P. Sicula. Dr. Gould (Otia, p. 215 
also describes P. decussata, coast of Georgia, 400 fm., U. 8. Coast eg 
111. The following descriptions of species, and notes on habitats and 
synonymy, have been collated from various American scientific periodicals, 
chiefly by the assistance of Mr. Binney’s ‘ Bibliography.’ 
In the ‘ American Journal of Science and Art,’ O.8., vol. xxxviil. p. 396, 
April 1840, Dr. A. A. Gould records the following species, said to be from 
“California.” His Z’rochus vittatus is not known :— 
Murex tricolor et bicolor. Trochus vittatus. 
Cardium Californianum. Bulimus undatus. 
In the ‘Annals of the New York Lyceum of Natural History,’ vol. iy. 
1846, No. 5, p. 165, Mr. John H. Redfield first described Triton Oregonense, 
Straits of San Juan de Fuca: plate 11. fig. 2. 
In the ‘ Proceedings of the Academy of Natural Sciences of Philadelphia,’ 
1848, vol. iv. p. 121, Mr. T. A. Conrad described new genera, and gave notes on 
Parapholas Californica, Cryptomya Californica, and Psammobia Californica, 
altering Osteodesma hyalina (nom. preoc.) into Lyonsia Floridana. In the 
same work, March 1854, vol. vii., Mr. Conrad described Cyathodonta undulata. 
He also states that Gnathodon trigonum, Petit, is probably identical with G. 
Lecontei, Conr.[?] (nom. prior), and alters genus Z'rigonella to Pachydesma.
