282 SKETCHES OP EUROPEAN ORNITHOLOGY. 



Plate XX. — The genus Procellaria, as constituted by Linnaeus, 

 included all the sea-birds furnished with tubular nostrils. Subse- 

 quently, it has been parcelled out, by naturalists, into several ge- 

 nera; three of which, Procellarittj Puffinus, and Thalassidroma, 

 contain European species. The concluding plate of Mr. Gould's 

 Fourth Pari, exhibits a nobly-executed figure of the typical species 

 of the Jirstj — the Fulmar Petrel, — Pr. Glacialis, — le Petrel Ful- 

 mar, Fr. The following are the generic characters of Procellaria, 

 as now restricted : Beak thick, dilated at the tip, sulcated : upper 

 mandible hooked ; lower straight and slightly truncated. Nostrils 

 united in a single tube. Legs moderate : a claw in place of the 

 hind-toe. 



The cautious and '^ tardigrade" Temminck, we may, in conclu- 

 sion, observe, distributed the species of the Linnaean genus, Procel- 

 laria, into three Sections or Sub-genera, respectively designated 

 Proper—', Puffin — , and Swallow Petrel, and comprehending the 

 following European species: 1. Pr. Glacialis ; 2. Pr. Puffinus, — 

 Anglorum, and — obscura ; 3. Pr. Pelagica, and — Leackii. And 

 it is, in our opinion, questionable whether the Dutchman's, after 

 all, be not the best, as it is evidently the most natural, arrangement. 

 The Fulmar Petrel constitutes the type of the new genus, Fulmarus, 

 of " Mr. Mihi Stevens."*

From a retrospect of our Analysis of the first four Parts of Mr. Gould's 

 splendid work, it wiU be seen that eighty-seven species of birds only have 

 yet been delineated, instead of one hundred, — twenty-five in each Part, — as 

 we were led, from the Prospectus, to anticipate. From the commencement, 

 we were of opinion that the Birds of Europe could not be completed in less 

 than twenty Parts. ]\f r. Gould has, at length, publicly confirmed the accu- 

 racy of our calculation. The last and twentieth Part will appear, we pre- 

 sume, in April, 1837.
