ICTERIDJJ. 
Shufeldt, R. W. On the Skeleton in the Genus Sturnella , with osteo- 
logical notes upon other North American Icteridce and the Corvidce. 
J. Anat. Phys. xxii, pp. 309-350, pis. xiv & xv. 
The representative of the Icteridce selected is Sturnella magnet neglecta , 
and the different sections treat of its skull, of the rest of its axial skeleton, 
of its sternum and shoulder girdle, of the pectoral limb, and of the 
pelvic limb. In all of these respects the species chosen is compared with 
other members of the same family and with several of the Corvidce. The 
conclusions drawn are : (1) that Sturnella represents a genus which un- 
doubtedly belongs to the Icteridce ; (2) that in its own family its nearest 
relation is Xanthocephalus , and that it is furthest removed from Icterus 
spurius , &c. ; (3) that outside of its own family it comes nearest to Cyano- 
cephalus, and possibly is not far from Picicorvus ; (4) that Icterus is 
nearest to Agelceus , and tends fmchwards ; (5) that Holothrus is a genus 
of Finches and is akin to Scolephagus among the Icteridce ; (6) that the 
Corvidce are properly divided into Corvince and Garrulince , but Pica is 
not Garruline ; (7) that Cyanocephalus lies exactly between the two sub- 
families. PI. xiv is skull and mandible of Sturnella ; pi. xv is skull and 
pelvis of Icteridce and Corvidce.
