516 BIRDS OF THE GALAPAGOS AlKHirELAGO—BTDOWAY. volxix. 



GEOSPIZA PACHYRHYNCHA, Ridgway. 

 (I'latci LVII, lig. !t.) 



Geospha pachyrhipicha, ItiD(iWAY, Proc. I'. 8. Nat. Mns., XVTII, No. lOCu, April 

 2'i, 18H(), p. 293 (Tower Island, Galapaj^os Aichipela<to; coUcctiou of Dr. G. 

 IJanr). 



S])ecifi<' eli(i>'<i<icr.s. — Similar to G. .sfrt )ih(i, (M)u](l,l)ntbill mucli tliieker 

 and broader at the base than in that lorni, in this iesi)ect nearly or (juite 

 equaling G. niagnirostris. 



Range. — Galapaoos Archipelago: Tower Island (IJaui' and Adams). 



Specimens of this form having been returned to Dr. Baur, to whose 

 collection they belong, 1 am not able to give a detailed description. 

 Fortunately, however, I made a careful drawing of the bill of one of 

 them, which shows the following measurements: Culmen, plus 0.90; 

 depth of bill at base, 0.88; width of mandible at base, 0.70; gouys, 0.40. 

 The bill is thus nearly if not (piite as thick at the base as that of G. 

 mafinirostris, but it is much shorter, thus greatly increasing its relative 

 thickness. 



GEOSPIZA CONIROSTRIS, Ridgway. 

 (Plate LVII, tig. 8.) 



Geospiza couirostris, Ridgway, Prof. V. 8. Nat. Mns., XII, No. 707, Feb. .'», 1890, 

 p. 106, fig. 2 (Ilood Islaml. (iala])agos Archipelago; coll. U. S. Nat. Mas.) 



Specific characters. — Similar to G. 

 fffrenua, Gould, but bill much more 

 elongated, much narrower, and culmen 

 less arched.
