Family CALLORHINCHWAE 



Characters. Snout rounded, with a curious flexible hoe-shaped proboscis, the 

 proximal part much compressed laterally and extending forward, the terminal part 

 bent downward as a thin transverse leaf-like appendage that is capable of spreading 

 widely sidewise or of folding rearward along its midline (Fig. 127); upper edge of 

 proboscis supported by the upper unpaired rostral cartilage, the lower edge by the two 

 smaller and lower paired rostral cartilages. Second dorsal fin separated widely from 

 first dorsal. Caudal fin much wider below its axis than above, with distinct lower anterior 

 lobe but without terminal filament; caudal axis bent somewhat upward, about at level 

 of origin of caudal fin. Anal fin separated from caudal fin by a deep narrow notch. 

 Gums in upper jaw with a series of transverse ridges. Margins of dental plates without 

 radial ridges. Claspers of males rod-like, with single long terminal cartilage, their tips 

 not dilated. Frontal tenaculum well developed on half-grown males and larger but not 

 visible on very young. Prepelvic tenacula more complex in structure than in other 

 chimaeroids, spoon-shaped, the blade armed along inner face with denticles having 

 several cusps; skin covering it thin, expanded on outer side as two frill-like lobes; a 

 globular gland near its base on inner side, opening to exterior by a short tube.^i' Open- 

 ings of prepelvic pouches longitudinal or nearly so, present on females though smaller 



118. For a more detailed account, see Leigh-Sharpe (J. Morph., 36, 1922: 208).
