 Curios, xviii, 739. Tab. 



This species is not anywhere described in the English language. I therefore 

 append the following, which I took from specimens in the Mus. Leyden : 



Crest very long, equal ; scales longer than high, other sc. small, keels not 

 prominent. 7 — 1 — 7 sc. on nape ; on rump, 7 or 8 — 1 — 7. Smaller lateral sc. 

 in a not wide band. Abd. sc. in 23 rows, rhombic. Sc. from ear to shoulder 

 granular ; tail compressed. Extended hind limb, near to ear. Interparietal 

 narrow ; 8 supraorb. Supercil. not separated. 3 pair frontonas., the poster. 

 often double ; 4 in the median row ; the frontonas. as broad as long. Head 

 sc. keeled. 



Olive-brown ; with or without traces of a light band on each side of back, 

 which are most distinct on tail ; sides with a band of brown speckles. Green 

 below, with 4 or 6 cross-bands of blue-white bordered spotlets ; obsolete ante- 

 riorly. Bluish on gular region. Head lighter, uniform ; feinus with two transv. 

 series of spots? Fem. with 2 longit..dors. stripes, and a distinct one on lower 

 part of each side. Transverse angulated brown bands behind white border, 

 from side to side. A yellow band on post, face of femur. Dors, crest very 

 small, scarcely on tail. Head sc. broad, keeled. 



CELESTUS Gray.

This genus, in my opinion, embraces the Diploglossinse, with normal extre- 

 mities, in which the frontonasal plates are fused together in one shield; it 

 therefore includes most of the species of Diploglossus, as understood by Gray. 

 Diploglossus was originally based by Wiegmann on D. m o n o t r o p i s and 

 D. fas ci at us, species in which the frontonasals are quite distinct. Both 

 are from the South American continent ; the first-named is the type of Camilia 

 [C. jamaicensis) of Gray. The correspondence of the Smithsonian Institution 

 has procured numerous additions to this genus, which are here added : 



A. Internasal plates confluent with frontonasals. 



I. Scales in 32 — 6 rows. 



Two frontals, one above the other ; two postnasals do. ; 



scales all 8 — 10 keeled; olive, sides black-spotted, steindachneri Cope. 



One frenal and postnasal ; scales smooth in front, keels 

 increasing to 16 on tail ; sides and limbs black ; 

 above olive, the scales black-edged chalyb^us Cope. 



Keels of the scales eight to ten ; one postnasal, two fre- 

 nals, both on labials ; meatus of ear large : anterior 

 limb two-thirds head. Brown, with blackish band 

 on upper part of each side pleii Dum. Bibr. 



Keels of the scales eleven, all equal, on posterior re- 

 gions ; anterior scales smooth, together in 36 rows ; 

 nasal plate extending to rostral ; two loreals, both 

 higher than long ; ear minute, head and limbs very 

 short, latter -75 former, and -2 from axilla to groin; 

 a blackish lateral band above, cross-lined before, 

 spotted behind dbgener Cope. 



Keels of the scales fifteen, all equal ; one postnasal, 

 two frenals, both on labials ; ear meatus small. 

 Serpentiform, fore limb five-sixths head. Brown, 

 with dark lateral band above sagr.e Coct. 



II. Scales in 41 — 2 rows. 



Keels 14; none larger; head narrow, sharp, muzzle 

 longer than interorbital width ; front plane ; parie- 

 tal separated from supraorbitals by two plates, 

 loreal longer than high ; gray, sides black, cross- 

 banded ; loreal higher than long phoxinus Cope.
