192 PKOCEEDINGS OF THE ACADEMY OF 



Pp. 80, 81, 90. There can be no doubt of the propriety of referring T. lugu- 

 bris Natterer, and P. melitensU Schembri, to pelagica L. Proc. tethys Bp., also 

 seems hardly distinct. 



Pp. 81, 90. Thalassidroma fasciolata Tschudi has been recognized by other 

 writers as valid. 



Pp. 84, 91. Oceanites segetki ex Ph. et Ldbk. is undoubtedly a synonym of 

 0. gracilis ex Elliot, as intimated in my paper. 



Pp. 87, 91. Fregelta Laicrcncii Bp. is probably a synonym of grallaria Bp. 

 ex Vieill. as Mr. Lawrence himself originally believed. The point cannot now, 

 however, be positively determined, as the specimen is lost. 



Pp. 88. 91. Bonaparte's identification of Linnaeus' Proc.frrgata, which I fol- 

 lowed, is by no means proven ; and in view of the uncertainty attaching to 

 Linnaeus' diagnosis (which may refer to some species of the genus Fregetia) it 

 may be as well to take our specific name from Latham's unequivocal indica- 

 tion of P. marina; calling the species Pelagodroma marina after Reichenbach. 



Fuffinese. 



Pp. 122, 142, 143. Genera " Thiellus " and " Nectris." The points in which 

 these groups differ from Pttffitius proper, are exceedingly trivial, as I state in 

 my paper. I am now indisposed to retain them, even on the plea of utility, 

 and would accordingly unite all their species under PvffinKs. 



Pp. 119, 141. Adamastor Bp. According to Mr. G. R. Gray the type 

 of the genus Friofinus of Hombron and Jacquinot is based upon the bird Bo- 

 naparte calls Adam, ti/pus, and it has priority over Bonaparte's designation. 

 If this be the case the three species should stand as Friof. cinereus, Friof. 

 gelidus and Friof. sericeus. 



Pp. 118, 141. 3Iajaqueus Reich. If Proc. Farkinsoni Gray, (Ibis 1864) is a valid 

 species, it may belong to this genus rather than to the fuliginous group of 

 ^Eslretata under which I have considered it. Additional data concerning it are 

 greatly to be desired. 



P. 121. Add Vaption gelidum Steph. Shaw's Gen. Zool. xiii. p. 245, to syno- 

 nyms of Adamastor gdidu-i. 



P. 123. Fiiffinus fuUginosus. I have received specimens from the Pacific 

 coast of North America which I cannot distinguish from the common Atlantic 

 bird. It is quite different from the species I have named Fiiffimis amanriso- 

 ma, p. 124. By a misapprehension of a remark of Dr. Kuhl, I erroneously 

 state that fidiginosa Forst., Descr. sp. 18, is a species of Xectr is : whereas I am 

 now satisfied it is the same as Kuhl's ?p. 12, which is the Plerodroma atlantica 

 of Bonaparte. Compare my remarks MnOi^v ^Fstrelatnfuliginosa. in \)a.Yt \y. of 

 these papers. KnhVs fidiginosa sp. 27, after Banks' tab. 23, is identified by Mr. 

 Gray with j^ccijica Lath. 



P. 126. N. carrieipes. On the authority of Dr. Schlcgel I placed c/n^rr?/,<ijuv. 

 Smith, and ^ama Bp. as synonyms of this species. Mr. Gray considers them 

 as referring to a species of Neciris or rather Ptiffinus not recognized in ray pa- 

 per, viz.: P. (ristis Forst. I am entirely unacfjuainted with this bird, if it be 

 a valid species. Bonaparte and Schlegel make it the same as tentiirosfris 

 Tcmm. 



Pp. 131, 144. A second specimen of Fiiffinus creatopus has been received 

 from the same locality. 



Pp. 141, 144. Procellaria nugax So], This unpublished specific name should 

 not take precedence over assimilis of Gould. 



Fulmare^. 



Add Fulmarus aniarc.tictis Steph. Shaw's Gen. Zool. 1825, xiii. p. 236, to the 

 synomyms of Thalassoica glacialoides. 



Add Daption aniarcticum op. oit. p. 242, to synonyms of Thalassoica antarc- 

 lica.
