NATURAL SCIENCES OP PHILADELPHIA. 201 



Young % . Crown red, many of the feathers having small spots of white, 

 occiput with a few scarlet feathers. Upper parts of body black, tinged with 

 brown, white spots on the primaries smaller than in adult. Back with a wide 

 longitudinal stripe of white, many of the feathers having black spots on their 

 edges. Upper tail coverts black. Under parts dull white. 



Younger $. Crown coppery red, front black, with white spots. Wing 

 almost clear brownish black, a few small spots only on the external webs of 

 primaries. Under parts dull white. No red feathers on occiput. 



Specimens occur occasionally which can be assigned to either this species 

 or P. villosus with equal propriety, and may be hybrids. 



1 6. Picus Jaddinei, Malherbe. 



This bird much resembles P. Harrisii, And., with which it is given as iden- 

 tical by Dr. Cabanis, in Journ. Orn. 1862, p. 175. There are in the Academy 

 Museum two specimens only, the better of which was brought by Mr. D'Oca 

 from Jalapa, Mexico, and both are the species described by M. Malherbe and 

 represented in his plate xxv. fig. 4, 5, though they appear to be in more ma- 

 ture plumage. The scarlet of the head is restricted to the occiput in both 

 specimens, and the two outer tail feathers are without black spots, though 

 the second feather has a black space at the base of the inner web. In young 

 birds it is unusual to find the clearly defined scarlet occiput, as in the present 

 specimens, for which reason, mainly, I dissent, though with some misgivings, 

 from Dr. Cabanis' conclusion. These specimens are much like the young of 

 Picus Harrisii, described above, except in the matter of the scarlet occiput. 

 They have the under parts of the body rather strongly tinged with ashy brown 

 for southern specimens of P. Harrisii, and very nearly as figured by M. Mal- 

 herbe, as above cited. 



17. Picus pubescens, Linnaeus. 



This little species, which is of common occurrence in North America, pre- 

 sents some variations in size, which fact I think has led to errors in descrip- 

 tions of supposed species. Both Picus meridionalis, Swains., and Picus medi- 

 anus, Swains., are very probably to be referred to this bird. Picus Lecontei, 

 Jones, is very probably an accidental variety, and so also possibly is Picus 

 leucurus, Prince Paul of Wurtemberg. 



This bird probably associates with P. Gairdneri in an intermediate region, 

 and produces hybrids. 



Is. Piers Lecontei, Jones.

The original and only specimen known of this species is in the Academy 

 Museum, though it belongs to Dr. Jones of Georgia, who is its describer. This 

 specimen is rather smaller than usual in specimens of Picus pubescens, in 

 which respect, as suggested by Dr. Jones in his description, it is like P. me- 

 ridionalis, Swains., but otherwise and in all other respects it is nothing more 

 than Picus pubescens, with three toes instead of four ! 



This bird has attracted some attention from European Ornithologists. The 

 Prince Bjnaparte made it the type of his genus Tridactylia, and M. Malherbe 

 is disposed to regard it as a true species. At present my opinion is that it is 

 an accidental specimen only of Picus pubescens, which opinion is subject, of 

 course, to immediate correction on the production of other specimens, which, 

 as Dr. Jones says, very candidly and properly, " will be necessary to establish 

 the species perfectly."
