The Canadian Field-Naturalist 



[Vol. XXXVI 



satisfactorily for all concerned by the immediate 

 establishment of bird reservations and goes on to 

 advocate the setting aside of a series of small 

 reservations among the archipelagoes fringing the 

 north shore. The residents of that coast them- 

 selves are well known to realize the urgent need 

 of giving protection to the birds which mean so 

 much to them. Almost to a man they believe that 

 a series of government bird sanctuaries should be 

 established in their midst. The creation of such 

 sanctuaries would meet with wide-spread popular 

 approval and the task of patrolling them would 



thereby be rendered comparatively easy. 



The time for the establishment of these sanc- 

 tuaries is at hand. Both the Government of the 

 Province of Quebec and the Dominion Govern- 

 ment are fully informed concerning the question 

 and have the necessary powers, and the creation 

 on this coast by joint action on their part of a 

 series of well-chosen reservations for birds, similar 

 to those now under joint protection at Perce and 

 the Bird Rocks, would be most welcome to all 

 concerned. There is much to gain and nothing 

 to lose by such action. 



NOTES AND OBSERVATIONS 



A Freshwater-Isopod New to Canada. 

 Since my article about these invertebrates was 

 published in The Canadian Field-Naturalist for 

 November, 1920, I have received from Prof. C. H. 

 O'Donoghue of the University of Manitoba, 

 Winnipeg, half a dozen specimens of Isopods 

 "collected in a small stream, about half a mile 

 northwest of the Biological Station at Departure 

 Bay (Nanaimo), B.C., late in July and in August, 

 1921. The locality is right on the border of an 

 old clearing that goes by the name of Hodgson's 

 Ranch." 



The specimens, when received, were dried up in 

 the vial, but as this is the first record of freshwater 

 isopods from western Canada, it was of importance 

 to get them identified. I could see that it was an 

 AseZh<s-species, but as it was little likely (see p. 

 148 in my article quoted above), that the central 

 and eastern form, A. communis Say occurred on 

 Vancouver Island, and as I am not faxTiiliar with 

 the Isopods found in the far western part of United 

 States, the specimens were sent to the U-S. Nat- 

 ional Museum, Washington, D.C., for identifica- 

 tion. Mr. C. R. Shoemaker there has kindly 

 identified them as Asellus tomalensis Harford, a 

 species hitherto known only from the three Pacific 

 States. 



The type was described by S. J. Holmes on pp. 

 321-23, pi. 37, in Proceed. California Academy of 

 Sciences, 3rd Series, III, 1904, from a single speci- 

 men, collected at Tomales Bay, California. Eight 

 more specimens, collected by the Harriman Alaska 

 Expedition at Lake Washington, near Seattle, are 

 referred by H. Richardson to this species and des- 

 cribed on pp. 431-33, figs. 487-89, of her Mono- 

 graph Isopods N.A. (Bull. 54,U.S.N.M., Wash- 

 ington, 1905). Specimens were also collected in 

 Tanner Creek, Portland, Oregon, in May, '1905, 

 by Dr. J. E. Benedict. 



The characteristics of the species are a light- 

 brown, somewhat mottled colour, and a narrow. 



elongate body. The first pair of legs are sub- 

 cheliform in shape, and their propodus (the joint "(j 

 next to the claw) is elliptical in outline, with the 

 inferior margin straight, and furnished with 

 numerous short spines or stiff hairs, by which 

 latter characters it can be distinguished from A. 

 communis. 



The finding of additional freshwater-isopods in 

 western Canada would have considerable interest, 

 and be much appreciated by the undersigned.

A Cladoceran New to America. ^On June 

 21st, 1922, in a collection of Entomostraca from 

 a marshy pool near the Biological Station, St. 

 Andrews, N.B., I found a specimen of Scaphole- 

 beris cornuta, Schoedler. I placed this specimen 

 in culture and it produced two parthogenetic 

 young which I raised to maturity. This species 

 has been known for a long time in Europe, but 

 this is, as far as I know, the first record of its oc- 

 currence in America. A. Brooker Klugh. 



Bumble-Bees on Bleeding Heart. When 

 I lived in Pilot Mound (1901-16) I grew Dielytra 

 spectahilis for many years and can verify Mr. C. E. 

 Johnson's observations. (Can. Field-Nat., Vol. 

 XXXVI. No. 3, March, 1922). The lovely pink 

 of this flower's quaint globes immediately lost 

 tone and faded as the result of the bumble-bee's 

 perforating jaws. H. M. Speechly. 



A Freshwater-sponge Named After Prof. 

 John Macoun. In the list of new species of 

 plants and animals named in honour of the late 

 Prof. John Macoun, of Ottawa, appearing in the 

 obituary in The Canadian Field-Naturalist for 

 September, 1920, p. 113, and at the end of his 

 autobiography (1922) p. 304, it is stated that the 

 list i s as yet imcomplete. 



I therefore take the liberty to call attention to
