LXVII. — Description of a new Snake of the Genus Glauconia, 

 from SomaUland. By G. A. BOULENGEK, F.K.S. 



Glauconia reticulata. 



Snout rounded ; supraocular present, small, longer than 

 broad; rostral one third the width of the head, a little 

 broader than the nasal, barely reaching the level of the eyes : 

 nasal completely divided, in contact with the prefrontal, 

 which is a little larger than the supraocular and much larger 

 than the frontal ; postocular, paiietal, and interparietal 

 large ; ocuhir bordering the lip, between two labials, t!ie ante- 

 rior of which equals the lower part of the nasal in size and 

 does not reach the eye; six lower labials. 14 scales round 

 the body. Diameter of body 38 times in the total length, 

 length of tail 9^ times. Dark brown above, with white 

 borders to the scales, forming a net\Tork ; white beneath. 



Total length lUO mm. 



A single specimen Irom Wagga, Goolis Mountains, near 

 Berbera, altitude 3000-4000 feet, from the collection of 

 Mr. G. W. Bury. Specimens of Glauconia Cairi were also 

 obtained at the same locality by Mr. Bury. This G. Cairi^ 

 long known from Egypt only, has of late been found near 

 Siiakim {Dr. J. Anderson), on the White Nile (Capt. S. 

 Florve?-), and at Harrar (Capt. Citerni, 1904: Genoa 

 Museum). 



The nearest ally of G. reticulata is G. narirostre, Peters, 

 from Lagos and the Niger, which differs principally in the 

 narrower rostral.
