38 MK. G. A. BOULBNGER ON THE REPTILES 



Gehyka, Gray. 



3. Gehyra oceanica, Lesson. 



Also a widely distributed species, occurring in the Moluccas, New Guinea, and many 

 Polynesian islands. Specimens from the Admiralty Islands, Lord Howes Island, Fiji, 

 Tongataboo, Samoa, Savage Island, and Earotonga Island, are in the British Museum. 

 Mr. Guppy collected specimens in the Shortland and Faro Islands.

The striking character in the physiognomy of this species is slenderness, the length 

 of the head being contained four times in the distance between the end of the snout 

 and the vent, and the diameter of the body nearly six times between those points. 

 The hind limb, when stretched forwards, covers three fifths the distance between axilla 

 and groin ; the fore limb reaches the centre of the eye. The head, which is hardly 

 distinct from the neck, is regularly oviform and very convex ; the snout measures once 

 and one third the diameter of the orbit, which equals its distance from the nostril or 

 from the ear-opening ; the upper surface of the snout is slightly concave medio-longi- 

 tudinally ; the ear-opening is very small and roundish. 



The upper surface of the head is covered with granular scales, which are minute on 

 the occiput and larger on the snout ; the rostral is quadrangular, a little more than 

 twice as broad as long, and with four short vertical clefts above, the median pair 

 being the most distinct ; on each side eleven or twelve small upper labials ; the nostril 

 is pierced between the rostral, the first supralabial, and three small nasals, forming a 

 slight swelling ; the granules bordering the labials are rather enlarged. The mental 

 is very small, smaller than the adjacent infralabials, not half the width of the rostral ; 

 its shape is pentagonal, narrowed posteriorly ; on each side eleven or twelve infra- 

 labials, the anterior distinctly larger than the supralabials ; three or four transverse 

 rows of very small polygonal chin-shields, passing gradually into the minute gular 

 granules. 



The body, which is feebly depressed, is covered above with uniform small 

 granules, smaller than those on the snout, and larger than those on the occiput. The 

 abdominal scales are juxtaposed round flat granules, the size of which is three or four 

 times that of the dorsal granules. The limbs are covered with granules similar to those 

 on the body. The digits, which are united at the base by a short web, are moderately 

 elongate and strongly dilated ; the inner is well developed ; the infradigital lamellae, 

 which are similar under the fingers and under the toes, are strongly chevron-shaped : 

 the distal lamella is, as usual, entire, the two or three next are divided by a median 

 groove, the others undivided; under the inner digit the lamellas are also chevron- 

 shaped, but without median groove.
