same author's description of A. lineatopus, that we cannot avoid suspect- 

 ing the latter name to be a synonym. The species is alluded to by Mr. Gosse 

 in the Naturalist's Sojourn in Jamaica, p. 225. The identification of this, and 

 of the A. opalinus of the same author, would have been much facilitated 

 by the introduction into the description of the latter, of the characters which 

 best distinguish species from species in this genus. The following may supply 

 some deficiencies : 



The head is rather large, and swollen round the occiput, so that the occipi- 

 tal plate is in a deep depression. The latter is small and separated from those 

 of the superciliary ridges by numerous small scales. The canthus rostralis is 

 very prominent and acute, nearly straight. There is a well marked depression 

 between them and the facial ruga?. The latter are acute, circumscribe an oval 

 depression containing three or four longitudinal series of keeled scales, and 

 converge upon the muzzle before disappearing. Nine to eleven palpebrals, all 

 keeled. The loreal rows are six ; superior labials eight, inferior ten. Two 

 anterior infralabials narrow, half the size of first inferior labials, larger 

 than those that follow, which are in three or four rows. There is a distinct 

 nuchal dermal fold ; about six dorsal rows of faintly keeled scales, larger than 

 the lateral. Superior brachial and pedal scales, and anterior antibrachial and 

 femoral, strongly keeled. Tail crest slight, verticils not very marked. The 

 hind leg extended will not reach beyond the anterior part of the orbit often 

 falling more or less short of it. The color that alcoholic specimens present is 

 a pale yellowish brown, with indistinct transverse brown markings on the 

 upper surfaces of the body, limbs and jaws. We can count five or six of these 

 transverse bands on the side between the axilla and groin; they are here often 

 crossed by a narrow light band proceeding from the shoulder, mostly obsolete 

 posteriorly. Goitre unspotted, pale orange in life, according to Mr. Gosse ; 

 the toes are of the slender type. From the muzzle to the vent measures about 

 two inches nine lines ; from the latter point to the end of the tail 5 in. 5 lin. 



The males of A. opalinus Gosse are smaller. The median dorsal rows 

 are less noticeably larger than the lateral, and are fewer in number. The 

 front is nearly plain, from the disappearance of the facial ruga?. The ventral 

 plates are smooth ; the superciliary plates are either in contact, or separated 

 by one row of scales, never by two, as is usually the case in maculatus. 

 In none of our specimens do the dark markings arrange themselves into trans- 

 verse bands, as in the latter, and the lateral pale stripe is much more con- 

 spicuous. 



In the female of A. maculatus the length from the muzzle to the vent is 

 1 in. 8 lines ; the tail 3 in. The dorsal region is pale, forming a more or less 

 distinct band ; there are two narrower bands on each side, more or less inter- 

 rupted, often indistinct. 



Numerous specimens of this species are in the Museums of the Smithsonian 

 Institute and Academy of Natural Sciences, which were sent to the former 

 from Jamaica by Mr. C. B. Adams. 



Anolis i o duru s Gosse, Ann. Mag. Nat. Hist. 1850, 344. Inhabits Jamaica. 

 The ventral plates in this species are usually smooth ; they are sometimes cari- 

 nate. Specimens exhibiting the latter structure have been described by Dr. 

 Hallowell as A. punctatissimus, Proc. Acad. Nat. Sci. Phil. 1856, 225. This de- 

 scription will prove valuable to those who have to depend on that of Mr. 

 Gosse, who gives too few of the essential characters for it to be readily recog- 

 nized. The A. heterolepis of Dr. Hallowell, op. cit. p. 230, is the female, the 

 locality " Cuba" being probably erroneous. Numerous specimens are in the 

 Museums of the Academy and of the Smithsonian Institute, those in the latter 

 .received from Mr. C. B. Adams, ^Nos. 5756, 5758.)
