WHITEAVES ON MARINE INVERTEBRATA, ETC. 
TEREBRATULINA UNGUICULA, Carpenter. Strait of Georgia, near Comox, in forty fathoms ; 
one small living specimen. Discovery Passage at station No. 7, a large ventral 
valve. Low tide, Johnstone Strait, one small living specimen; and Johnstone 
Strait at station No. 10, two small living specimens. 
The Terebratula unguicula of the late Dr. P. P. Carpenter was regarded as merely 
a local variety of the European T! caput-serpentis by the late Dr. Thomas Davidson. 
A series of adult and perfect examples of 7! unguicula, dredged by Mr. James Rich- 
ardson in 1876 in the Strait of Georgia, was sent by the writer to Dr. Davidson, for 
examination, in the fall of 1884. In a letter dated November 29, 1884, Dr. Davidson 
writes :—‘ The specimens named Terebratulina unguicula are only a variety of T°: caput- 
serpentis. 1 will describe it in my monograph” (one on recent brachiopoda, then in 
course of preparation) “as Terebratulina caput-serpentis, var. unguicula, Carpenter. I 
compared al] your Vancouver examples very minutely with a number of European 
specimens of Linne’s species, and feel confident that 7. wnguicula is not a distinct 
species.” 
LaquEeus CALIFORNICUS. Koch. Discovery Passage at station No. 7, one dead but perfect 
J 8 P 
shell and a large dorsal valve. Johnstone Strait at station No. 10, five living 
adult specimens and several young. Race Passage, Johnstone Strait, two small 
but living specimens. 
TEREBRATELLA TRANSVERSA, Sowerby. (—T! caurina, Gould.) Low tide, Strait of Georgia, 
many small but living and strongly ribbed specimens. Entrance to Malaspina 
Inlet, at low water, one living specimen. Discovery Passage at station No. 7, 
three small living specimens and one dead shell. Johnstone Strait at station 
No. 10, two adult living shells and one small one. Queen Charlotte Sound 
at station No. 12, one small living shell, and at station No. 18, five small, living 
specimens. 
At these localities, some of the specimens have strong, radiating ribs, while 
others are almost entirely smooth, but there are intermediate gradations between 
the ribbed and the smooth forms, which latter is the one represented by Sowerby 
in the “Thesaurus Conchyliorum,” as the type of T! transversa. 
LAMELLIBRANCHIATA. 
& 
PLACUNANOMIA MACROSCHISMA, Deshayes. Entrance to Malaspina Inlet, at low water; 
three small, living specimens attached to Ostrea lurida. Strait of Georgia at station 
No. 2, two rather small, living specimens. Quatsino Sound, Vancouver Island, one 
large and two small living shells. 
OSTREA LURIDA, Carpenter. Entrance to Malaspina Inlet, at low tide, two living speci- 
mens. A number of good specimens of this species, which were said to have been 
taken near Comox, were purchased in Victoria, Vancouver Island. Bradley Lagoon, 
Blunden Harbour, Queen Charlotte Sound, on the mainland side, abundant. This 
last is the most northerly locality yet recorded for oysters on the coast of British 
Columbia.
