SNAKES 



TYPHLOPS MANNI, new species 



r^/pe.— U.S.N.M. No. 109634, from Harbel, Republic of Liberia, 

 March 10-July 17, 1940. 



Diagnosis. — Agrees with T. p. functatus (including its Liberian 

 synonyms of lihenensis Hallowell, nigrolineatus Hallowell, and inter- 

 media Jan) in possessing 26 midbody scalerows. It differs from both 

 T. J), functatus and T. leucostictus in its broad and trilobate snout, lat- 

 eral nostrils, absence of an ocular, and in its midbody diameter being 

 included in its total length 40 times (instead of 24-36 times in pimctatus, 

 45 in leucostictus). In addition, it differs from leucostictus in possess- 

 ing 26 (instead of 22) midbody scalerows, a preocular as wide as a 

 nasal, incompletely divided nasal, and — though probably of little sig- 

 nificance — completely hidden eyes. 



Description. — Snout prominent, trilobate as seen from above, 

 rounded, without obtuse horizontal edge ; rostral half the width of the 

 head ; nasal swollen, semidivided, the suture extending from the second 

 labial to the nostril, which is lateral ; preocular present, as broad as the 

 nasal, much broader than either of the small scales which might be 

 termed an ocular, the lower in contact with the third labial; eyes 

 hidden; only 3 upper labials. Midbody scalerows 26. Diameter of 

 body included 40 times in total length, tail broader than long, ending 

 in an obtuse spine. 



Coloration. — ^About to slough. Above, silvery gray, base of each 

 scale with a transverse brown spot. Below, yellowish gray, with a 

 few fine black flecks. 



Measurements.— Total length 343 (338 + 5) mm.; diameter at mid- 

 body 8.5 mm.
