rior part of the body; gastrosteges 193 ; anal divided ; urosteges 43 pairs, 

 the second to the sixth entire. Rostral 3.3 mm. long, 2.3 mm. broad, 

 portion visible from above equals 1.5 mm., its distance from the fron- 

 tal 2.5 mm.; internasals 2 mm. long; prefrontals 2 mm. long; parietals 

 5.2 mm. long; two preoculars, two postoculars, and one subocular; 

 two anterior temporals, two posterior on the right and three on the 

 left side. 



Anatomy. — Head 15 mm. long; snout 5 mm. long; diameter of the 

 eye 1.8 mm., its distance from the mouth 1.8 mm. 

 Calliophis japonicus Guenther. 



Type. — Callophis boettgeri Fritze.*^ 



Mus. Senckenbergianum No. 9395. Tokuchimura, Okinawa, Loo 

 Choo Islands. Male; total length 384, tail 37 mm. 



Squamation. — Temporals one anterior, one median, and two pos- 

 terior on the right, and one anterior, two median, and two posterior 

 on the left side. 



Coloration. — Five longitudinal stripes, broader than the intervals; 

 the lateral pair terminate at the base of the tail. Body with nine, 

 tail with one cross-band. 



The records of the color pattern show that the longitudinal mark- 

 ings vary in number and width from a single narrow vertebral line 

 to five stripes that are broader than the intervals. Furthermore, 

 between the extremes there exist the following unbroken series of 

 intermediate designs: 



A median stripe. 



A median stripe with trace of the intermediate pair. 



A median stripe and the intermediate pair. 



A median stripe, the intermediate pair, and a trace of the lateral 

 pair. 



A median stripe, the intermediate, and the lateral stripes, narroAver 

 than the intervals. 



A median stripe, the intermediate, and the lateral stripes, broader 

 than the intervals. 



Specimens possessing these various color patterns do not have 

 associated with them the slightest diversity in structure. The ser- 

 pents with five stripes that are broader than the intervals have been 

 elevated to specific rank as C alio phis boettgeri Fritze. The name has 

 been correctly assigned to synonymy^ and should be allowed to 

 remain there.
