AND BATSACHrANS OF BAEBARY. 145 



2. CORON'ELLA GIRONOICA, Daudin, 1803. 



Snout scarcely prominent ; rostral much broader than deep, just visible from above ; 

 suture between the internasals half as long as that between the praefrontals ; frontal a 

 little longer than its distance from the end of the snout, a little shorter than the 

 parietals ; loreal longer than deep; one pra> and two postoculars ; temporals 2-|-3 ; 

 eight upper labials, fourth and fifth entering the eye ; four lower labials in contact 

 with the anterior chin-shields, which are as long as the posterior. Scales in 21 rows. 

 Ventrals 200 ; anal divided ; subcaudals 59. Grey-brown above, with blackish spots ; 

 a pair of elongate blackish spots on the nape ; a black streak on each side of the head, 

 from the nostril, through the eye, to the angle of the mouth ; a dark band between 

 the eyes, crossing the prefrontals ; a black line below the eye, on the suture between 

 the fourth and fiftli upper labials. Lower surfaces yellowish (in spirit), with quadran- 

 gular black spots. 



Total length 450 miUim., tail 80. 



The above description is taken from a single female specimen from the city of 

 Morocco, described in 1874 by Dr. Boettger, to whose kindness I am indebted for 

 examining it. The species was recorded from Tangier by Gervais, who probably took 

 for it the common Macroprotodon cucuUattis, which does not appear in his list. Boettger 

 records it from Tlemsen, in the Province of Oran. Nothing more can be said as to its 

 distribution in Algeria since the records of authors may be based on the closely-allied 

 C. amalice. M. Lataste did not meet with it in Algeria. C. girondica inhabits the 

 south of France, Spain and Portugal, and Italy. 



Figured in Bonaparte's 'Fauna Italica,' and in Jan's Icon. Gen. Ophid, livr. 17, pl.iii.

2. Lytorhtnchus, Peters, 1862. 



Maxillary teeth 6 to 9, posterior much longer than anterior; mandibular teeth 

 subequal. Head slightly distinct from neck, with cuneiform projecting snout ; 

 eye moderate ; pupil vertically elliptic ; rostral large, four-sided, projecting, concave 

 beneath ; nostril an oblique slit between two nasals. Body cylindrical ; scales smooth, 

 in 19 rows, without apical pits ; ventrals obtusely angulated laterally ; tail moderate ; 

 subcaudals in two rows. 



A single species in Barbary. 



1. Lytoehynchus diadema, Dum. & Bibr. 1854. 



Eostral angularly bent, with straight horizontal edge, detached on the sides, the 

 portion visible from above as long as its distance from the frontal ; suture between the 

 internasals much shorter than that between the prefrontals ; frontal nearly as long as its 

 distance from the end of the snout, slightly shorter than the parietals; a small, squarish 

 loreal ; one or two prseoculars, with or without a subocular below ; two postoculars ; 

 temporals l-j-2 or 2-|-3; seven or eight upper labials ; fourth, fifth, or fourth and
