IMPEXXES. 625 



B. Tail relatively short, composed of 20 



feathers ; upper tail-coverta short. Bill 

 moderately long, not very stout, the 

 eulminicorn being divided "by a groove 

 from the latericorn, which is not much 

 swollen towards the base ; feathering at 

 the angle of the gape leaving the tomia 

 and greater part of the base of the man- 

 dibles exposed. Superciliary bands of 



short golden feathers, united at the back [p, 644. 



of the crown 4. Megadyptes, 



C. Tail very short, composed of 16, 18, or 



20 feathers, which are almost entirely 

 concealed by the longer upper tail- 

 coverts ; groove dividing the eulminicorn 

 from the latericorn inconspicuous. 



c. Basal part of mandibles entire : size 



small 5. EuDYPTULA, p. 645. 



d. Basal part of mandibles furrowed by [p. 648. 



numerous longitudinal ridges 6. Sphen'iscus, 



surrounding the eye was specially noted. So far as is known no species (;f 

 Penguin has a conspicuous naked space round the eye : and if the descriptions 

 of these two writers are merely based on birds observed from a distance, 

 it seems not improbable that they may have mistaken some species of 

 Cormorant. 



The bill and head of the bird figured by Sonnerat are certainly more like 

 those of some species of Cormorant. 



Coues considers A. torquata, Forst., to be " a variety of demersus," but this 

 view seems obviously untenable. 



2. Diomedea chilensis, Molina, HUt. Kat. Chili, p. 210 (1786), ed. Gall. 



p. 217 (1789). 

 Aptenodytes chiloensis & A. chilensis, Gmel. S, K. i. pt. ii. p. 559 (1788) 



[based on Molina's descriptions]. 

 Pinguiuus chilensis, Bonnat. Tabl. Encycl. Meth. i. p 30 (1790). 

 Aptenodytes raolinas, Latham, hid. Orn. ii. p. 881 (1790). 



These are also said by Coues to be descriptions of the young of S. demersus. 

 It is just possible that Molina may have had before him the young of S. hum- 

 holdti, but even this is very doubtful. 



3. New-Holland Pinguin, Latham, Gen. Hist. x. p. 388 (1824). 

 Sphenisous nova-hollandiffi, Stsph. in Shaw's Gen. Zool. xiii. pt. i. p. 68 



(1825). 

 This may be founded on an immature specimen of C. pnchyrhynchus or 

 M. antipodum, but the meagre description makes it impossible to identify the 

 species referred to with certainty. 



4. EuDYPTES sp.? — " Intermediate in size bet wepn the Emperor and Black- 

 throated Penguins, having a yellow patch under each eye and a red supraciliary 

 crest extending backwards on each side to a length of 3 to 4 inches." A 

 rookery of this Penguin was met with on the South Orkneys by Capt. Larsen, 

 and two specimens were preserved but afterwards lost. Believed to be aa 

 umlescribed species. — Cf. Donald, P. E. Soc. Ediub. xii. p. 176 (1894).
