91. Macoma EXPANSA, Carpenter. 
Macoma (? v.) expansa, Cpr., Rept. Brit. Assoc., 1863, p. 639, (Aug., 1864) ; and 
Proc. Acad. Nat. Sci. Phila., 1855, p. 56. 
This is the name applied by Dr, Carpenter to some shells obtained 
by Dr. Kennerley in Puget Sound. Dr. Carpenter himself noted the 
close resemblance to lata — calcarea, and I suspect that M. expansa will 
prove to be only a variety of that species. 
92, Macoma INCONSPICUA, Broderip and Sowerby, sp. 
Tellina inconspicua, Br. and Sby., Zool. Jour., vol. iv., pt. 15, p. 363 (1829); and Zool. 
Voy. Blossom, p. 153, pl. xli., fig. 6 (1839). 
Very common and variable. Found everywhere in sand between 
tides. 
Jeffreys and others have united this species with Macoma lata. By 
a similar process of lumping together allied forms, the number of species 
of Macoma may be considerably reduced, but there seems little doubt, 
to my mind, as to the specific distinctness of all the forms above enu- 
merated. On this coast, at any rate, they do not seem to intergrade at 
all. 
93. Macoma CARLOTTENSIS, Whiteaves. 
Rept. Prog. Geo. Surv. Canada, 1878-79, p. 1968, fig. 1 (1879). 
This species is only known to us from the original description and 
specimens. The latter were obtained by Dr. Dawson in 1878 in “ Virago 
Sound in from eight to fifteen fathoms, abundant.” 
94, MACOMA YOLDIFORMIS, Carpenter. 
Rept. Brit. Assoc., 1863, p. 639 (August, 1864); and Proc. Acad. Nat. Sci. Phila., 
1865, p. 55. 
Described from specimens from Puget Sound (Kennerley) and 
Vancouver Island (Swan). It has since been obtained by Dr. Newcombe 
and myself by dredging in various localities on both the east and west 
coasts of the island, and it is probably widely distributed. 
The “ Macoma, n. sp.,” mentioned by Dr. Newcombe, in his list, as 
taken at Clayoquot Sound, seems to me to be identical with this species. 
95. MAcoMA INFLATULA. Dall. 
(See note under Angulus Gouldii.) 
(Hdalina subdiaphana, Cpr., is in Dr. Newcombe’s catalogue, with 
the note, “One living specimen at low water Clayoquot Sound.” The
