This species is clearly distinct from the ordinary form of Cuba and 

 the Bahamas. The comb of the third posterior digit found in the other 

 species of the genus is here represented by a few distinct scales of identi- 

 cal form with, but rather larger size than the others, on the border of the 

 toe, the gradation of proportions being complete. The small granular 

 scales of the muzzle form also a marked difference. I mention here 

 that the combs of the C. Iccoloplia and C. nubila are like those of the G. 

 cornuta, and not like those of the G. carinata, as stated in my synopsis 

 of the species of Cyclura in the Proceedings of the Amer. Philosoph. 

 Soc, 1885, p. 262.* 



Liocephalus carinatus Gray. 



New Provideni'e, Wood; Abaco, Townsend; 14566. Also Cuba. 

 Lioceplialus loxogrammus, sp, uov. 



The species belongs to the group with only two frontonasal plates on 

 each side, with the L. raviceps and L. personatus. From all of these 

 species it differs considerably in color, and in some structural peculiar- 

 ities, as follows : 



The dorsal scales are larger than in L. raviceps. There are eleven 

 rows on the nape between the external angles of the parietal scuta. 

 The scales are, however, not subequal, as in L. personatus and L. trigemi- 

 natus ; but those on the sides are much smaller than those of either the 

 back or belly. Thus in the last-named species I count thirty-five rows 

 between points just above the axilla and groin. In L. loxogrammiis 

 there are fifty-seven rows. The dorsal and caudal crests are not so 

 elevated in the L. loxogrammus as in the species named, although the 

 caudal is more elevated than the dorsal. The posterior frontonasals 

 are remarkably large, as in the L. raviceps, and the head plates are all 



*In describing a new species of Cacliryx ( C. erythromekis) Dr. Boulenger, in the P. Z. 

 Soc. Loudon, 1886, p. 241, finds my criticism of Mr. Bocourt's disposition of that ge- 

 nus apparently self-contradictory. Mr. Bocourt wished to identify Cachryx with Hop- 

 locercus, and I declared them to be not alike, meaning by this, not identical. I had 

 previously asserted some likeness of Cachryx to Hoplocercus, which it has, of a su- 

 perficial kind, but at the same place I stated, "this genus is decidedly iguaniform," 

 and compared it with Ctenosaura. As Dr. Boulengerplaces Cachryx between Cteno- 

 saura and Hoplocercus, it is evident that his opinion of its affinities is the same as my 

 own, expressed some twenty years ago.
