CATALOGUE OF SPECIES, WITH NOTES, 
BRACHIOPODA. 
The recent Brachiopoda, and especially the American species, have 
been well worked up by Dr. Dall. To his numerous papers on the sub- 
ject in the American Journal of Conchology (vols. vi. and vii.) and 
in the Proceedings of the Academy of Natural Sciences of Philadelphia, 
the student is referred for extended notices of our British Columbian 
forms. 
TEREBRATULINA, D’Orbigny. 
1. TEREBRATULINA UNGUICULA, Carpenter, sp. 
Terebratula unguicula, Cpr., Rept. Brit. Assoc., 1863, p. 636 (Aug., 1864); and 
Proc. Zool. Soc. London, 1865, p. 201, fig. 1-4. 
This species is now generally considered to be only a variety of 7° 
caput-serpentis, Linne, sp. (Anomia caput-serpentis, Linn., Syst. Nat. 
ed. xii., vol. i., pt. 2, p. 1153, no. 236, 1767) which is, of course, the 
older name. Our species or variety was first described as from ‘San 
Diego 6 fms., Monterey, not rare in 20 fms. Cooper, Neeah Bay (valve) 
Swan, Vancouver, Forbes.” It is not rare at Victoria and Departure 
Bay and has been dredged by Dr. Dawson in the Straits of Georgia, 
Discovery Passage, Johnston Strait and Forward Bay. Probably it 
will be found to occur throughout the province. Generally specimens 
are found attached to stones or dead shells dredged in from 1 to 100 
fathoms, but on one occasion [ obtained a fine series attached to the 
hairy epidermis of a living specimen of Tritonium Oregonense. Dr. Dalt 
states that specimens from deep water are generally larger than those 
from near low water mark. 
TEREBRATELLA, D’Orbigny. 
2. 'TEREBRATELLA TRANSVERSA, Sowerby. sp. 
; Y> SI 
Terebratula transversa, Sby., Proc. Zool. Soc. London, 1846, p. 94: and Thes, 
Conch., vol. I., p. 261, pl. 72, fig. 114-115 (1846) = Terebratula caurina, 
Gould, Proc. Bost. Soc. Nat. Hist., vol. iii., p. 347 (December, 1850) ; and 
U.S. Expl. Exped., p. 468. figs. 582-582c (1852). 
This is an extremely common shell with us. It occurs in two dis- 
tinct forms—a smooth deep-water form, which is the typical transversa, 
and a highly sculptured form occurring in thousands between tides, and

poda of Alaska and the adjacent shores of Northwest America.” Proc. Acad. Sei. 
Phil., 1877, p. 155 et seq.
