only ; b, echinating spicule, spinous ; c, equianchorate flesh- 

 spicule, navicular, much bent upon itself. 



Fig. 44. Renierajibulata, Schmidt : rt, skeleton-spicule of one kind only ; 

 b, flesh-spicule, bihamate. 



Fig. 45. Cliona abyssorum, skeleton-spicules of two forms : «, large, 

 pin-like ; b, smaller, acerate ; c, flesh-spicule, spiro-sinuous. See 

 more magnified view of the latter in fig. 33, PL XIV. 



Fig. 46. Gummina Wallichii : a, central canal ; b, rows of tubercles ; c, 

 more magnified view of tubercle. 



N.B. In the upper half, for convenience, the tubercles are 

 omitted. 



Fig. 47. Forcepia colonensis. Scale l-12th to 1-GOOOth inch. 



N.B. On one side the spines are partly omitted for conveni- 

 ence. This figure is intended for comparison with fig. 32, a, 

 PL XIT. : but it should be remembered that it is drawn to a 

 much larger scale, not being half so long as fig. 32 in reality, 

 although stouter and more markedly spined.

 (here the spines are again omitted for convenience) ; c, two- 

 branched form. 



XXXII. — Description of a new Species of Lizard of the Genus 

 Celestus. By A. W. E. O'Shaughnessy, Assistant in 

 the Natural-History Departments of the British Museum. 



Celestus bilobatuSj sp. n. 



Body slender, elongate, rounded ; limbs short, the anterior 

 not reaching to the eye, the posterior not quite to the middle 

 of the side. Ear very small, almost closed. Head obtuse ; 

 muzzle rounded, shorter than the interorbital width of the 

 head. Supranasals two pairs 5 internasal large, broad ; frontal 

 broad, oblong ; small interparietal, smaller fronto-parietals, 

 large parietals, and small occipital. A small scale or two scales 

 wedged in between parietals and supraorbitals. Five supra- 

 orbitals, the fifth triangular, entirely on the flattened upper 

 surface of the head and abutting on the internasal. Two 

 narrow plates, one elongate, coming forward from the line of 

 the supraoculars, are wedged in between the fifth supraorbital 

 and internasal and the several postnasal or lateral plates, of 

 which there are two postnasals proper, one over the other, and 

 two consecutive loreals. Rostral very short and very wide. 

 Supralabials eight. Teeth conspicuously bilobate. Scales in 

 forty-one longitudinal series, twelve- to-fourteen-keeled, without 

 prominent central keel ; eighty-six scales in the median ventral 

 series ; the preanal scales much larger, in three rows, about 

 twelve. All the scales rounded. Tail much longer than body 

 and head.
