ANATOMY AND AFFINITIES OF CCEBEBIDM— LUCAS, vol.xvh. 



are sliowii iu the figures. Tbeir arrangement in the Cterebidse is very 

 much that shown by Myadestes, except that in CertJiiola 4 and 5 are 

 merged iu one. 



Fig. 2.— Hypotarsi of (1) Phceornis obscura,- (2) Merula migratoria; (3) Myadestes solitarius; (4) 

 Hemignatlms olivaceus; all vfiiy much enlarged. The numbers in (2) refer as follows: [1] Foramen 

 for tendon of flexor longus hallucis; [2] flexor per/oratus digiti IV and slip to base of first phalanx of 

 digit III; ['i] flexor perforatus digiti III; [i] flexor perforans digitorum pro/undusj [b] flexor perforans 

 et per/oratus digiti II, and flexor per/oratus digiti II. 



The tongue is forked in Goereba and Gerthiola, brushy in Certhiola, 

 laciniated or feathered in Gcereba. There is a decided difference 

 between the tongues of Goereba coerulea and G. cyanea, as is shown by 

 the figures. 



Fig. :j.— Greatly enlarged views of tip of tongue of (1) Olossoptila campestris; (2) Acanthorhynchus 

 tenuirostris; (3) Goe reba cyanea ; (4:) Gcereba coerulea; ib) Gerthiola bahamensir; number one is viewed 

 from below, the others from above. 



Gcereba cierulea comes near having a tubular tongue, but although 

 tlie edges approach one another they do not meet except at the lacini- 

 ated tip. In Gerthiola the tongue is simply grooved down the center. * 



Glossoptila is noteworthy, from the fact that it has a trifid tongue, a 

 thin, fiat, j)ointed strip being produced between the laciniated branches. 



* It makes a decided difference whether the tongue is examined in a moist or dry 

 condition, for in drying the onter edges curl ujjwards and render the tongue more 

 tubular, or gutter-like, than in its natural state. The specimens from which the 

 figures in this paper were made were all kept wet while they were being drawn.
