THE HERPETOLOGY OF HISPANIOLA 233 



scale-rows converge on the back. Tail scarcely compressed. A pair 

 of postanals in the male. 



"Coloration (in alcohol). — Body color pale olive green above, 

 chromium green below; very faint indications of sepia crossbars on 

 the nape of the neck; the body-scales above and below the light 

 dorsolateral line only slightly tinted with sepia; tail without cross- 

 bars or markings of any kind in the adult male; hind limbs immaculate; 

 fore limbs with a few small sepia spots on the upper part, and faint 

 traces of crossbars on the wrists; mental shield edged with sepia; 

 sutures between the labials sepia; remainder of throat heavily dotted 

 with large sepia spots in about ten or twelve irregular transverse rows 

 from the chin to the chest; sides of head from tip of snout to above the 

 ear (in the type specimen) pale olive, almost immaculate; two small 

 brown spots just behind the ear, followed by three prominent cres- 

 centic sepia markings, the two posterior ones the largest and corre- 

 sponding to the hollows behind the skinfolds occurring between ear and 

 shoulder; a black axillary spot below the last of these spots; top of head 

 pale olive, without markings. 



"Measurements. — Snout to vent, 64 mm.; head to posterior ear, 

 16 mm.; tail (reproduced), 78 mm.; foreleg, 25 mm.; hindleg, 49 

 mm.; width of head, 12 mm. 



"Variation. — Among the series of nine there is considerable varia- 

 tion, as one might expect. The dorsal scales from occiput to above 

 vent range between 57 and 70, with a corresponding variation of 13 

 to 17 dorsals in a head-length. There are about 44 to 52 scales around 

 the body, but as is always the case, this count is never made twice 

 alike, due to the slanting of the lateral rows. The lamellae under the 

 fourth toe vary between 23 and 28. The length of the hindleg is 

 between 74 and 83 per cent of the combined length of head and body. 

 The median snout scales are constantly present as a patch of 2 to 4 

 scales. There are six supraoculars in every case but one, in that one 

 there are five large and two small supraoculars. Not every adult 

 male shows the crescentic sepia or black shoulder patches which give 

 the subspecies its name. F.M.N.H. 139, for instance, lacks the 

 black shoulder patches and the axillary spot; it is, however, heavily 

 pigmented with sepia on the side on the head and neck above a faint 

 pale lateral stripe beginning on the loreal region. Below this lateral 

 light stripe is another intense concentration of sepia on the jaw in 

 front of the ear, while the sutures of some of the labials are heavily 

 marked with sepia. The dorsal region of this specimen is likewise 

 suffused with sepia, and traces of dark crossbands are apparent almost 

 to the sacral region." 



Relationships. — While this subspecies is related to Leiocephalus per- 

 sonatus mentalis, the type locality of which is Jovero, D. R., it is still 

 more closely related to louisae from Saona Island.
