and the upper side of the limbs is thinly checkered with black ; the enlarged 

 spinules and tubercles are all pure white. There is a dark streak between 

 the snout and the eye, posteriorly there are three dark lines, one going to the 

 occiput, the second to the ear, the third to the angle of the mouth ; and 

 generally there are one or two more below the eye, giving the side of the 

 head quite an ornament Jtl appearance. Labials spotted with white. Chin 

 and throat powdered with brownish dusky, remainder of lower side uniform 

 pale, more or less distinctly tinged with fleshy ; in males more markedly so 

 than in females. In the very young lizard (about one inch long) the lateral 

 black spots along the back, and the median black line behind the ej^e are 

 most distinctly marked, in other respects it does not differ from the adult. 



Hob. — Preparis Island. I obtained five specimens, two apparently 

 adult males and two females, and one young ; all were found on the ground 

 between old decaying vegetable matter. One of the largest specimens with 

 perfect tail, measures : head and body 1*13, tail 1*37 = 2"5 inches. The 

 length of the hind limb equals the distance from the shoulder to the groin. 



I have great pleasure in connecting with this very interesting new 

 species the name of the able Commander of the " Scotia," Capt. G. W. 

 Wicks, who piloted us most skilfully through the labyrinth of small and 

 large islands. 



MOCOA MACEOTYMPANUM, n. Sp. 



Body moderately slender, head flattened above, muzzle rather attenuated 

 and prolonged. Anterior frontal in contact with the rostral, separating the 

 two elongated nasals, and posteriorly just touching the vertical, which is 

 rather shortly, obtusely angular in front, and gradually attenuated behind. 

 Four enlarged supraciliaries, preceded and followed by a smaller shield. The 

 two anterior occipitals (? accidentally) united, the median one roundly 

 angular in front, attenuated and contracted behind, the two laterals narrow, 

 in contact with each other behind the median shield. Four pairs of scales 

 behind the occipitals enlarged, occupying the whole width of the neck. 

 Seven upper labials, the fifth under the orbit, six narrow lower labials. 

 First chin-shield single, the second is a pair in contact, third separated by a 

 small shield, fourth pair somewhat smaller. Lower eyelid with a trans- 

 parent disk. Ear opening very large, rounded, with a perfectly smooth edge 

 all round, the tympanum being distinctly visible. Body in the middle 

 surrounded by twenty-two longitudinal series of smooth scales, six series 

 being on the back ; they are slightly larger than those at the sides. About 

 fifty -two scales along the edge of the lower side, counted between the fore 

 and hind limbs. A pair of moderately enlarged prse-anal shields. Median 

 row of sub-caudals slightly enlarged. Limbs proportionately developed, 

 with the toes very slender.
