GLYPHORHYNCHUS. 175 
short, the culmen and gonys are gently curved downwards and upwards, and both 
maxilla and mandible expand laterally towards the tip and are rounded at their ends ; 
the nostrils are completely overhung with a membrane, leaving the opening a narrow 
curved slit lying along the lower edge of the nasal fossa. 
The range of the genus extends over the greater part of Tropical America, G. cune- 
atus being a denizen of the low-lying virgin forests.

Our first Central-American specimen (shot by Salvin at Yzabal, in Guatemala, on 
19th June, 1859) was referred with doubt to G. cwneatus”, but on the receipt of more 
examples from Choctum in Vera Paz in January 1860, the Guatemalan bird was named 
by Sclater and Salvin G. pectoralis, in a paper read before the Zoological Society on 
22nd May, 186014. In 1862 ?° Mr. Sclater, overlooking the previous description of the 
same bird, re-described one of the Choctum skins as G. major, and in the same year 
referred to a Mexican skin under this name *!. It is now pretty generally admitted that 
the Central-American bird cannot be distinguished from the Continental form, and 
there is certainly no tangible difference between the Yzabal bird and others from the
