180 WHITEAVES ON MARINE INVERTEBRATA, ETC. 
MESALIA RETICULATA, Mighels. (—Turritella lactea, Moller, and Mesalia lacteola, Carpenter.) 
Dredged rather abundantly, living, in the Strait of Georgia at station No. 5, in 
Discovery Passage at station No. 8, in Johnstone Strait at station No. 10, in 
Queen Charlotte Sound at stations Nos. 12, 13, 14 and 17, and in Quatsino Sound 
at station No. 20. 
BITTIUM FILOSUM, Gould. Common, living, at low tide, in Malaspina Inlet, Strait of 
Georgia; in Discovery Passage, between Seymour Narrows and Elk Harbour; in 
Johnstone Strait, the Goletas Channel, and Queen Charlotte and Quatsino Sounds. 
BITTIUM MUNITUM. (—Cerithiopsis munita, Carpenter.) Queen Charlotte Sound at station 
No. 12, ten fine and mostly living specimens. The writer is indebted to Mr. W. 
H. Dall for the suggestion that this shell is probably a Bittium rather than a 
Cerithiopsis, and that the Cerithiopsis columna of Dr. Carpenter is only an abnormal 
form of it. ‘ 
LITTORINA SITCHANA, Philippi. A common littoral species throughout the district. A few 
specimens of it were dredged in Discovery Passage, at station No. 7. The late Dr. 
Jeffreys regarded this shell as only a local variety of the European L. rudis. 
LITTORINA SCUTULATA, Gould. With the preceding species, but apparently not quite so 
common. 
LACUNA SOLIDULA, Loven. (—L. carinata, Gould.) A few living specimens were taken at 
or near low water in Alert Bay, B. C., and it was dredged living, but in very small 
numbers, in Discovery Passage at station No. 8, and in Queen Charlotte Sound at 
stations Nos. 12 and 15. Dr. Jeffreys was of the opinion that this shell is a variety 
of L. divaricata, Fabricius (—L. vincta, Montagu), of northern Europe. 
BARLEEIA SUBTENUIS, Carpenter. Queen Charlotte Sound at station No. 12, one living 
specimen. 
SURCULA PERVERSA, Gabb. Queen Charlotte Sound at station No. 16, one large, living 
specimen, an inch and three-quarters in length, and another smal] but living shell ; 
and station No. 17, an immature but living specimen. 
This large and remarkable species, which is invariably sinistral, was previously 
dredged alive by Mr. James Richardson in from thirty to seventy fathoms in the 
Strait of Georgia. In the young state the test is nearly smooth and covered by a 
very pale, greenish-grey epidermis, and the body whorl is encircled by two spiral 
bands of a faint reddish-brown tint, one next to the suture and the other a little 
below the middle. 
BELA FIDICULA, Gould. Johnstone Strait at station No. 10, four specimens; Queen 
Charlotte Sound at stations Nos. 14 and 16,—one living specimen at the first, and 
two full-grown, living shells at the second. 
BELA TABULATA. (—Mangelia tabulata, Carpenter.) Queen Charlotte Sound at station 
No. 16, two specimens. Perhaps only a variety of the last named species. 
BELA VIOLACEA, Mighels, var. (Teste Dall.) Queen Charlotte Sound at station No. 14, one 
living specimen. :
