in the G.g. A. (31 July 1819. p. 1203). Mus cahirimcs is quoted, 

 without page, iu JVonv. Diet. Hist. Nat. xxix., 1819, p. 70, and 

 Khinolophus tridens on p. 253 (but in the latter instance the 

 paye of the text of Geoffroy's ' Egypte' is quoted). Ichneu- 

 mon edivardsii, I. gersius, and others are also referred to by 

 pages, on pp. 212 etc. of the same work. I regard this part 

 as issued in 1818. There is a very interesting proof of 

 pp. 99-144 preserved in the Gray Tracts, Brit. Mus. (Nat. 

 Hist.). It is paged 1-46 and has for signature 7 ff. N., and 

 is dated 'I'lmprimerie imperiale, Mars 1813." This was sent 

 by Geoffroy to Dr. J. E. Gray, and in a letter which accom- 

 panies it, ivitJiout date, Geoffroy says : — " Je lui fais part dans 

 cette livraison d'un imprime tire dans cette forme a deux 

 exemplaires, et c'est la seule consideration que je sais faire 

 valoir pour rendre moins indigne de lui ce faible don de ma 

 reconnoissance." Engelmann, Bibl. Hist. Nat. 1846, p. 373, 

 quotes 1813. 



Vol. II., Manimiferes by Geoffroy and V. Audouin, pp. 733-743, 

 and Mammif eres carnassiers by V. Audouin, pp. 744-750. 

 In Ferussac, Bull. Sci. Nat. xix., 1829, p. 337, there is afoot- 

 note which states "La partie de I'ouvrage qui contient ce 

 memoire et le suivant [i.e. 'Mammiferes" and ' Mammif eres 

 carnassiers '] vient seulement de paraitre." This seems to be 

 conclusive, and the date of these two parts may be accepted 

 as 1829. 



Vol. I., part 1, pp.53-62: VoL.I.,part4, pp.245-250, and Vol. II., 

 pp. 1-98, deal with Botany and Mineralogy, and do not come 

 under this enquiry. 



I am indebted to Mr. Boulenger, Dr. Anderson, and Mr. B. B. 

 Woodward for many valuable suggestions during the progress of 

 this enquiry, which has extended over several years. 



6. Notes upon the Anatomy of Phaethon. By Fkank E. 

 Beddakd, M.A., F.R.S., Prosector to the Society. 



As the genus Phaethon is one of the least known among the 

 Steganopodes, and as it is regarded by Furbringer as the most 

 primitive form of that group, I am particularly grateful to 

 Mr. J. J. Lister, of St. John's College, Cambridge, for allowing 

 me to dissect a specimen. 



I identify the specimen (a $ ) with Phaethon flaviroslris of 

 Brandt ', as described by Mr. Lister in a paper upon the fauna 

 of Christmas Island^. 



As to external characters, the oil-gland, as in other species of 

 Phaethon, is densely tufted ; the skin is very emphysematous ; I
