be more rigidly determined. Further, more accurate figures of the 

 brist'es and other parts are required." In a recent paper in the 

 " Annals of Natural History " (London, September, 1901) Prof. 

 Mcintosh publishes some notes on at least six species of marine 

 worms procured by Dr. Whiteaves, and though the British autho- 

 rity is the most eminent expert in that group of invertebrates, and 

 has diagnosed myriads of specimens from all parts of the world 

 and established numberless new species, yet of these specimens of 

 Canadian Phyllodocid^e only one species is in every detail identical 

 with a European form, viz., the ubiquitous Phyllodoce j^rcenlandica, 

 CErsted," taken abundantly on Bradelle Bank and 15 miles south- 

 east of Bonaventure Island. Othtr specimens closely resembled 

 P. laminosa, Sav., and others again differed from both. Of three 

 species of Eteone, one, E. spefsbergensis, Mgrn., was unquestion- 

 able, but two other species approached either E. lentigera, Mgrn., 

 or E. chierea, Webs, and Bened. An appropriate means of escape 

 from the dilemma so often presented by Canadian species is to call 

 them Canadensis or to do as Professor Mcintosh did in the case of 

 the graceful Polynoid worm, Malmgrenia ivhi/eavesh\ or as Professor 

 Verrill did in naming a pretty shell CeriUiielLa whiieavesii, and a 

 unique zoophyte Actinopsis tohiteavesii. 



The author in his prefatory remarks points out that most of 

 the invertebrates were obtained on the floor of the sea or collected 

 in littoral regions, hence such widely scattered species as the 

 aberrant Chaitognath Sagitta does not occur in the catalogue, 

 though pelagic Ctenophores like Pleurobrachia, Bolina and Idyia 

 are mentioned on the authority of certain United States observers, 

 and the interesting occurrence of the lovely sea-butterfly {Clione 

 limacma, Phipps) is recorded near Belle Isle Straits on the autho- 

 rity of Dr. Deeks, other specimens being also referred to, from 

 more northerly regions. 



The usefulness of this catalogue, if it is permissible to make 

 the suggestion, would be vastly increased by the addition of an 

 index. An index would save time and would certainly facilitate 

 reference to its pages by those not familiar with marine zoological 

 nomenclature, and many such, it is to be hoped, will use this 

 excellent work of reference.
