confined to the sides as in the latter. That it is a connecting 

 link between the two is evident, for several of the Key West 

 specimens unmistakably approach crassirostris, while others 

 vary in the direction of novcboraccnsis . With the latter, in- 

 deed, the large series before me* establishes a perfect intergra- 

 dation. This seems to be effected within a narrow latitudinal 

 belt, all my specimens from Northern Florida being essentially 

 similar to those from the United States at large, the intermedi- 

 ates coming from Miami and the keys between that point and 

 Key West. A bird from Cozumel Island is apparently typical 

 noveboracensis , while two Bermuda specimens show only slight, 

 and perhaps accidental, peculiarities. 



Several of the Key West examples used in the above compar- 

 ison were collected by Mr. C. J. Maynard, to whom the new 

 bird is dedicated. 



RECENT LITERATURE. 



Sclater's Catalogue of the Ccerebidae, Tanagridae, and Icteridae. — In 

 the eleventh volume of the British Museum Catalogue of Birdsf Dr. P. L. 

 Sclater treats the three strictly American families Ccerebidae, Tanagridae, 

 and Icteridae — groups to which, as is well known, he has for many vears 

 given special attention. Of the family Ccerebidae (Guit-guits, or Honey 

 Creepers), 70 species are recognized, of which 63 are represented in the 

 collection of the British Museum by 672. specimens. The members of this 

 family are of small size, mostly of brilliant color; some are closely related 

 to the Mniotiltidae, from which they may, however, be distinguished by 

 "the more slender unnotched bill and filamentous termination of the ex- 

 tensile tongue"; others are with difficulty separable from the Tanagridae. 



Of the great group Tanagridae 377 species are admitted, all but 20 of 

 which are represented in the British Museum Collection by 3413 speci- 

 mens. Thirty-three species are referred to the genus Eupkouia, 61 to 

 the genus Calliste, 32 to Chlorospingus, and 35 to Buarremon. The total 

 number of genera is 59. 



* About one hundred and fifty specimens, chiefly from the collections of the National 

 and Cambridge Museums.
