large, soft and not very closely aggregated. The tongue of 

 F. nehidosa (text-fig. 19) differs somewhat from that of the last 

 species. The wide dorsal bounding zone of small papillae contains 

 more fungiforms. The spinous patch begins far from the apex of 

 the tongue and reaches nearer the middle of the oral part of the 

 dorsum. In other respects the tongues are similar. In F. viver- 

 rina the dorsal bounding zone extends along the anterior third of 

 the oral part of the dorsum : it is narrow and has few fungiforms. 

 Clavate papillae are absent. The spinous patch begins a short 

 distance behind the apex of the tongue, but lies entirely in the 

 anterior third of the tongue. Its constituent papilla are slender 

 and inconspicuous. The papillae behind the spinous patch are 

 arranged in a central and two lateral tracts, and the conical

papillae on the base of the tongue are narrow, pointed, and discrete. 

 In the tongue of F. hengalensis the dorsal bounding zone is relatively 

 wide and has well-developed papillae fungiformes. No papill® 

 clavatae are present. The spinous patch begins some distance 

 behind the apex of the tongue and extends to the middle of the 

 oral part of the dorsum ; its papillae have strong points. The 

 central and lateral tracts of papillae behind the spinous patch are 

 just distinguishable ; and the papillae on the pharyngeal part are 

 long, slender, and discrete. In F. pardalis (text-fig. 19) the 

 dorsal bounding zone is narrow and has few fungiform papillae. 

 The spinous patch does not extend as far back as the middle of 

 the oral part of the dorsum. In other respects it is similar to
