292 REPORT ON ZOOLOGY, MDCCCXLIV. 



the European Woodpeckers into three groups, the green, black, and party- 

 coloured Woodpeckers, their osteological diversities being separately stated 

 in detail. Of foreign species the author has only been enabled to compare 

 the skeletons of Picas flavescens and the skulls of P. campestris, melano- 

 clilorus, rnlricatus, Candidas, favifrons, albirostris, lineatus and passerims; so 

 that this portion of the work is as yet imperfect. Among the latter he dis- 

 tinguishes a group of the brown-yellow Woodpeckers by the type afforded in 

 P.flavescem, the structure of whose cranium accords with that of P.flavicans 

 tinnunculus, and Jmnana ; besides a group of the dark -backed Woodpeckers 

 by P. candidus and flavifrons. The author observes that under these five 

 groups, so far as the evidence of external characters may warrant us, the 08 

 species of the Petersburg museum admit of being brought ; although there 

 are some with whom it will certainly prove difficult to determine under which 

 of these they ought respectively to be numbered, and what species constitute 

 the alliance-members of all the groups, seeing that the latter have been 

 separated as distinct genera, and by Swainsou made into no less than twenty. 

 In the second division the author treats of the plumage of the Woodpeckers 

 and adds some remarks upon the caudal gland, the mucous glands, and the 

 lingual apparatus. 



A new species, Colaptes meatcanoicles (!), has been raised by Lafresnaye, 

 in the 'Rev. Zool.' p. 42, and at p. 81, the sexual differences in Picus mela- 

 nopogen are determined by the same author. Hartlaub remarks, at ibid. p. 

 402, that the home for Hemicircus rulif/inosus, Swains., is not Senegambia 

 but Malacca. 



PSITTACIN^. New species of Fraser : Psittacus Timneh, from Sierra 

 Leone, and Ph/clolopln/s citrino-cristatus (Ann. of Nat. Hist, xiv, p. 452.) 

 Ibid, xiii, p. 475, of Gould ; Psittacus flavinuchus, from South America. 

 In the 'Birds of Australia' he figures Eiiphema pulchella and pdropldla, n. 

 14 ; Platycercus Brownii, n. 16. Brehm's ' Monographic der Papageieu' has 

 reached the fourth part.
