176 Zoology. 



PL 21. "Bill entirely black, the iris of the eye brown, pupil 

 black. Feb. 1st, 1769. Lat. 59° 00'." 

 Procellaria lugcns, Banks MSS. (cf. Kuhl, Beitr., p. 144). 

 = (Estrelata brevirostris (Less.) ; cf. Salvin, Cat. B., 

 xxv., p. 409. 

 PL 22. The same as 21. 



Kuhl gives the MS. name of P. lug ens, Banks, but he himself 

 refers the figures to Procellaria grisea [nee Gmelin]. The 

 earliest published name seems to be that of (Estrelata brevirostris 

 (Less.). 



PI. 23. " The beak fuscus, the lower mandible paler and 

 blueish; the feet of the same colour. Feb. 15, 1769. 

 Lat. 48° 27', Long. 93°." 

 Nectris fuliginosa, Solander MSS. 



= Puffinus griseus (Gm.) ; cf. Salvin, Cat. B., xxv., p. 386. 

 PI. 24. " The beak blue grey towards the back, and the point 

 black ; the legs and feet the same colour as in the 

 Procellaria cyanopedo. Nectris munda. Feb. 15, 1769. 

 Lat. 48° 27', Long. 93°." 

 The late Mr. Osbert Salvin was of opinion that this pencil- 

 sketch represented the species described by Giglioli and Salvadori 

 as Puffinus elegans (Ibis, 1869, pp. 67, 68); cf. Salvin in 

 Rowley's Orn. Misc., i., pp. 256, 257, pi. xxxiv. (1876); id., 

 Cat. B., xxv., p. 385. 



PL 25. "The face and throat white as marked of[f] on the 



figure ; the whole body above and below f usco-palido ; the 



belly, the feet, whitish w 1 a cast of blue, the nails 



white. Dec. 23rd, 1768. Lat. 37° South. Diomedea 



exulans." 



This figure probably represents the young of Diomedea 



exulans (cf. Salvin, Orn. Misc., i, p. 238 ; id., Cat. B., xxv., p. 



442). 



PL 26. " The bill entirely black, the iris of the eyes yellow- 

 brown, the pupil black ; the skin that goes along the 

 beak from the head pale violet clouded w* pale brown. 

 Feb. 1st, 1769. Lat. 59° 13'. Diomedea antarctica." 

 = Plioebetria fuliginosa (Gm.) ; cf. Salvin, Orn. Misc., 

 i., p. 238 ; id,, Cat. B. 5 xxv., p. 453. 

 PL 27. "The beak, excepting the back of the upper mandible 

 and part of the under one, is a dirty greenish white. 

 Feb. 3rd, 1769. Lat. 57° 30'." 

 Is Diomedea prof uga, Solander MSS., which is Thalassogeron
