190 The Ottawa Naturalist. [November 



some errors were no doubt unavoidable, though others it is more 

 difficult to account for, especially such an obvious misprint as 

 " Dr. J. W. Whiteaves," instead of the correct and familiar "Dr. 

 J. F. Whiteaves," in the heading of the review. "Marine Worms" 

 in large type on p, 167 requires elision, as also the figures 428, 

 opposite the word " Brachiopoda." Canadian waters are rich in 

 Invertebrates, but they would be a veritable zoological Eldorado 

 if they harboured 428 species of Brachiopods. The actual number 

 of Biachiopod species is 3, and the Polyzoa 1 15, the figures 3 and 

 115 being one line below their proper place. The 9th line, on 

 page 170, states exactly the reverse of the fact and the sentence 

 should end : " the Dog-whelk {Purpura lapillus, L.) arouses no 

 such question." It is difficult to account for the statement in lines 

 20, 21, and 22, that Litorina rudis is recorded only for our more 

 northern coast extending into Hudson Bay, unless it is due to the 

 circumstance that the review was based on notes, made while 

 reading Dr. Whiteaves' Catalogue, and the author's statement 

 was overlooked that the species has a widespread abundance as 

 well as a northern distribution. Happily these errata do not affect 

 the reviewer's attempt to express the genuine feeling of apprecia- 

 tion with which the publication of the Catalogue will be regarded 

 in scientific circles at home and abroad. 



Readers will do well, however, to make note of the following 

 errors in the review : — 



p. 165, line 5— "J. F. Whiteaves, LL.D.," &c., not "J. W. Whiteaves." 

 p. 167, line 28 — " Marine Worms" to be elided. 

 „ 33-" 3 "not "428." 

 „ 34-" 115" not '3." 

 ,, ,. 35— " "5" to be elided. 



.> i> 43 — After Arachnida insert '^{Pyc?iogo?iida).'' 

 p. 170 ,, 10 — " arouses such," to read " arouses no such." 

 ,, ,, 12 — '■'■ Uturea'^ not '■'■ literea." 



,, ,,22 and 21, to be elided and to read " not only for our more 



northern coast extending- into Hudson Bay: but is abundant almost every- 

 where o\'\ rocks, sea-weeds, &c." 



p. 171, line 15 — '■'■ spitsbergensis" not '' spetsbergensis." 

 ,, ,, 19 — '■^ Canadensis" not '^^ Ccxiiadensis."
