NATURAL SCIENCES OF PHILADELPHIA. 193 



Bibliographical Appendix. 



It may be well to give in this connection a synopsis of the works of some 

 of the older authors, as far as they relate to the subject in hand. The earlier 

 authorities to be particularly consulted in a study of the Procellariidse* are 

 the following : 



Linn-eus, Syst. Nat. ed. 10 (1758.) 



In this edition, the first in which species are presented, there are named (p. 

 131) three species ; sc. pelagica, (type of genus Procellaria ;) wquinoctialis and 

 capensis. 



Linnjeus, Syst. Nat. ed. 12, vol. i. (1766.) 



1. Proc. pelagica, p. 212. 



2. Proc. fregata,-p. 212. I followed Bonaparte's authority in referring this 

 name to the species subsequently named marina by Latham ; but there seems 

 to be nothing in the Linnajan diagnosis requiring this identification ; the name 

 being very probably based upon some species of the genus Fregetta as now re- 

 stricted. 



3. Proc. glacialis, p. 213, = Fulmar us glacialis Leach. 



4. Proc. lequinoctialis, p. 213, = Majaqueus lequinoctialis Reich. 



5. Proc. capensis, p. 213, = Daption capensis Steph. 



6. Proc. puffinus, p. 213,= probably P. anglorum (Ray.) Temm. Bas been 

 identified also with P. Kuhlii Boie, and P. major Fab., and almost every other 

 Atlantic Puffinus. 



Gmelin, id. Linn. Syst. Nat. vol. i. part. ii. (1788.) 



7. Proc. obscura, p. 559. Oue of the smaller Puffini, the habitat of which is 

 given as " insula nativitatis Christi." Now universally applied to the common, 

 bird of the Atlantic, called obscura by Vieillot, Nouv. Diet. p. 423, in 1817. 



8. Proc. pacifica, p. 560. Not identified with any other known species. A 

 large Puffinus, from the island of Euopoa. 



9. Proc. cozrulea, p. 560, = Halobsena carulea Bp. 



10. Proc. vittatus, p. 560, = Prion vittata Lacp. 



11. Proc. urinatrix, p. 560, = Pelecanoides urinatriz Lace*p. 



1. Proc. pelagica, p. 561. Variety B. is probably fictitious. 



2. Proc. fregata, p. 561. Same as that of Linnams. 



12. Proc. furcata, p. 561, = Oceanodroma furcata Reich. 



13. Proc. fuliginosa, p. 562. Based upon Latham's species of this name,, 

 and not yet identified. A small species, eleven inches long, with a forked 

 tail ; from Otaheite. Generally supposed to be a species of Thalassidroma. 



14. Proc. desolata, p. 562. Now recognized as a valid species of JEstrelata. 



15. Proc. nivea, p. 562, = Pagodroma nivea Bp. 



1 6. Proc. melanopus, p. 562. Not identifiable, except opinionatively. Evidently 

 some species of ^Estrelata. Said to come from North America, which would 

 make it referrible to JE. hxsitata. Description applies in most respects to 

 mollis Gould. 



3. Proc. glacialis, p. 562, = Fulmarus glacialis Leach. The var. B. is the 

 Thalassoica glacialoides (Smith) Reich. 



*The indications of the Diomedeinx are generally so definite that the consideration of them 

 may be here omitted.
