438 BATRACHIANS AND REPTILES OF BAHAMA ISLANDS. 



Strongly keeled. The external parietals are not twice as wide as the 

 internal, and tlie latter are in contact posteriorly for half tlieir length, 

 reducing tlie interparietal to a very small size. Temporal scales mod- 

 erate, keeled ; those of the auricular border not larger than the others. 

 Supranasals narrow, in contact with the rostral shield, and generally 

 separated by a small internasal; this is followed by a small first inter- 

 frontonasal, which separates the small anterior frontonasals, and this 

 by a small second interfroutonasal, which generally does not prevent 

 the mutual contact of the posterior frontonasals. The tail is com- 

 pressed, except at the base. The extended hind limb reaches the eye. 

 The prehumeral fold is strong, and has some large scales on its edge, 

 foreshadowing the collar scales of collared forms. 



Color olivaceous above, light olive yellowish below. There is a dark 

 lateral band, which is very indistinct behind the axilhe. Anterior to 

 this point it is black, and is subdivided posteriorly two or three times 

 by vertical rows of yellow spots. A small yellow spot on the anterior 

 auricular margin. There are numerous short blackish lines on the sides 

 and dorsal region along the sutures between scale-rows, which are 

 therefore directed upwards and backwards. These are most distinct in 

 females. The males have, iu addition, a row of blackish spots on each 

 side on the nape. Top of head brown. The belly is marked by cross-rows 

 of small brown dots three or four scales apart ; the scales iu the intervals 

 more or less dotted with white and pink. Legs brown, spotted above.

l!fumerous specimens from Kum Key ; No. 14569. 



Bouleuger in the Vol. II of the Catalogue of the lizards in the British 

 Museum regards L. raviceps as the same as L. macropm. They are, how- 

 ever, different s})ecies, belonging to different sections of the genus. The 

 L. trigeminatus is probablj^ the immature stage of L. personatus^ with 

 which Dr. Boulenger properly unites it.
