 the genus Glottis that occurs in Britain, is of a very slender 

 form, having the body rather elongated, the neck long, the 

 head small, oblong, narrowed before, and much rounded in 

 front. The bill is half as long again as the head, very 

 slender, compressed toward the end, straight until beyond 

 the middle, when it inclines slightly upwards. The nasal 

 groove and that of the lower mandible extend nearly to the 

 middle ; the upper mandible has the ridge rather flattened 

 at the base, but with the sides convex beyond the groove, 

 the edges inflected, with a narrow groove, the tip narrowed, 

 and slightly decurved; the lower mandible with the angle 

 long and extremely narrow, the dorsal line slightly ascending, 

 the edges inflected, with a narrow groove, the tip narrow. 



Internally both mandibles present a narrow and deep 

 groove, their sides being thick. The tongue is narrow, 

 grooved above, sagittate and papillate at the base, horny 

 toward the end, thin-edged, and pointed ; its length an inch 

 and a quarter. The mouth is very narrow ; the oesophagus 

 six inches and a half long, of the nearly uniform width of four- 

 twelfths ; the proventriculus oblong, with cylindrical glan- 

 dules. The stomach is elliptical, an inch long, ten-twelfths 

 in breadth, compressed, with the lateral muscles very large, 

 the epithelium dense and rugous. The intestine is three 

 feet two inches long, and varies from four-and-a-half-twelfths 

 to two-and-a-half-twelfths in width ; the coeca are cylin- 

 drical, two inches and a half in length, and two-twelfths in 

 width. 



The eyes are rather small, their aperture measuring two- 

 twelfths and a half! The nostrils are linear, direct, per- 

 vious, two-twelfths and a half long. The aperture of the 

 ear is elliptical, three twelfths and a half in its greatest 

 diameter. The feet are very long and slender; the tibia 

 bare for an inch and a quarter, with thirteen anterior scu- 

 tella ; the tarsus compressed, with thirty scutella ; the hind 

 toe very small and elevated, with six scutella ; the anterior
