ORNITHOLOGY. 



upper part of the neck, extending from the posterior angle of one orbit 

 to the other, and near the orbits is of a greenish-gray color ; the upper 

 part of the Ijack between the wings, the wing-coverts, and upper tail- 

 coverts, are aquamarine green ; the first quill is black, the others are 

 blue on the outer, and black on the inner webs ; but in proportion as 

 the quill becomes more internal, the first of these colors encroaches 

 upon the second, so much that it is very extensive on the internal 

 webs of the secondaries; the tail-feathers are black beneath and above, 

 like the quills ; the lower mandible is yellowish; the upper mandible 

 brownish horn-color ; tarsi, toes, and nails, are the same color." 



Total length, about ten and a half inches (" 266 millimetres") ; 

 tail, four inches ("101 millimetres") ; bill, two inches ("51 millime- 

 tres") ; tarsus, eight-tenths of an inch (" 2 centimetres"). 



" We possess two young specimens, brought also from the Mariannes 

 Islands, by Messrs. Quoy and Gaimard. Both are colored beneath like 

 the adult, but in one the green of the back is deeper, in both, the head 

 is green, with white spread here and there upon the feathers, and as 

 this last color occupies a part of the upper part of the neck, it results 

 that these two individuals have a cervical collar of a white color. 



" This species appears to me very exactly established. It has in- 

 timate relations with that which Mr. Gould has more recently described 

 and figured in the ornithological part of the Voyage of the Sulphur, 

 under the name of Halcyon saurophaga. It is distinguished from it, 

 among other characters, by rather smaller size and a shorter and nar- 

 rower bill." 



Subsequently, in the same article, cited above, Pucheran states that 

 DaceJo albicilla. Lesson, is the same bird, and that the varieties A and 

 B, of that author (Traite d'Orn. p. 247), are the two young specimens 

 alluded to by him, as above given. 



This species we have never seen. We do not, however, regard Cu- 

 vier's name as entitled to any consideration, unless a description by 

 him has been published, which is not the case to our knowledge, but 

 would regard Lesson as the proper authority. For a similar reason 

 we have not adopted Alcedo rujiceps, Cuv., for Halcyon cinnamomeus, 

 Swainson. 



5. The following species are included in the genus Todh-ampJius by 

 Bonaparte, in Conspectus Avium, p. 156, and by Reichenbach in VoU- 

 standigste Naturgescliichte, but in our opinion, erroneously :
