46 ROYAL 80CIKTY OF CANADA 



91. Macoma expansa, Carpenter. 



MacoitKi (i V.) r.tjjanso, Cpr., Kept. Brit. Assoc, 1S(W, p. (i3!>, (Aug., 1H()4) ; and 

 Proc. Acad. Nat. Sci. Phila.. IWio, 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 onlj' a variety of that species. 



92. Macom.a. inconspicua, Brodei-ip and Sowerby, sp. 



Telli'iKi !n<oiis])icua, Br. and Sby., Zool. Jour., vol. iv., pt. 15, j). 8H3 (1829); and Zool. 

 Voy. Blossom, p. 158, pi. xli., fig. (i (183!)). 



Very common and variable. Found cverj^where in sand between 

 tides. 



Jeffreys and others have united this species with Macoma lata. Hy 

 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- 

 raerated. On this coast, at any rate, they do not seem to intergrade at 

 all. 



!)3. ^Eacoma Carlottensis, Whiteaves. 



Rept. Prog. (leo. Surv. Canada, 1878-7!), p. 19()B, tig. 1 (187!)). 



This species is onl}- known to us from the original description and 

 specimens. The latter were obtained by r)r. Dawson in 1878 in " Virago 

 Sound in from eight to tifteen fathoms, abundant." 



94. Macoma yoldiformis, Cai'penter. 



Kept. Brit. A.ssoc. 18(W, p. (Wtt (.\ugust, 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 jnyself 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 inflatlla. Dall. 



(See note under Angulus Goiddii.) 



(Eaalina subdiaphana, Cpr., is in Dr. Newcombe's catalogue, with 

 the note, "One living specimen at low water Clayoquot Sound." The
