naso-rostrals with the fronti-naso-rostrals, by the presence 

 of an odd frontal, a supraorbital, and an anteorbital, by 

 the unusually large first infralabial, and the much larger 

 number (ten) of the preanal pores. 



A. violacea, Ptrs. (Monatsb. 1854, p. G20) which agrees 

 in the position and proportion of the rest of the scutella, in 

 the number of the anal pores, and the segments of the anal 

 lip, is distinguished by its single pair of fronti-naso- 

 rostrals, by the extraordinary length of the frontals, which 

 are quite three times as long as broad, and of both tem- 

 poral plates, which by themselves cover the whole of the 

 temporal region. 



b. Nasal shields small, separate above, on the side of a large 

 swollen rostra! shield. 



4. BRONIA. 



Head ovate, rather convex ; rostral shield very large, 

 hemispherical, with the small nasal shields inserted in 

 notches on its hinder edge, which is placed over the front 

 labial ; crown convex, rounded on the sides, covered with 

 two pairs of shields ; the front pair square, the hinder 

 smaller, triangular, with a small triangular occipital shield 

 on its outer side ; eye-shield triangular ; labial shields ^g, 

 the second upper and front lower large ; gular shield single, 

 square, with a cross series of shields behind it. Body 

 cylindrical ; lateral line well marked ; the dorsal shields 

 elongate, narrow ; the ventral ones rather broader, smooth ; 

 preanal pores four ; the preanal shields six or eight, the 

 central pair the largest, the lateral ones very small. Tail 

 blunt.

Bronia brasiliana. 



1. Bronia brasiliana. B.M. 



Pale brown ; dorsal shields with a dark central spot. 



Bronia brasiliana, Gray, P. Z. S. 1805, p. 448, f. 1, 2. 



Hab. Tropical America ; Santarem, on the Amazons. 

 (Bates, B. 11.) 



C. Lateral and dorsal lines not defined, or the lateral lint 

 only visible on the hinder part of the body ; rostral 

 shield small ; nasal shields small, far apart, placed on 

 the side of the high rostral. 



5. SAREA. 

 Head conical ; rostral narrow,higher than broad. rounded 

 in front, placed behind the triangular nasal ; crown with 

 two pairsof shields ; the front largest, elongate, the hinder 

 trigonal; eye-shield triangular; the labial shields t-), the 

 second upper and lower labial shields very large, the others 

 smaller, "with one large gular plate. Body slender, tin- 

 dorsal scutella square, as long as broad, with a dark cen- 

 tral dot ; two central longitudinal series of ventral scutella 

 broader than long, smooth, white ; the lateral line very 

 indistinct, scarcely visible except on the hinder part of the 

 body. Preanal pores four ; preanal shields six, square. 

 The eyes are slightly visible through the shields.

Amphisbsena coeca, Cuvier, 7i. A. p. 773. 



Dam. Sc Bibr. Erp. Gen. v. p. 492. 

 Sarea caeca, Gray, Cat. Tort. Sfc, B. 21. p. 71, 1844; 

 P. Z. S. 1865, p. 449. 



Hab. West Indies; Porto Bello (Capt. Aastin, R.N., 

 B. M.) ; St. Thomas's (A. H. Riise, B. M.). 



The specific name is not characteristic, as the eyes are 

 as much seen through the shield as in many Amphisbas- 

 nians. 



2. Sarea? imrocens. 



Eyes not visible ; rostral shield triangular, not quadran- 

 gular (as in A. punctata) ; two fronti-naso-rostral shields ; 

 rostral shield low and smooth, not keeled (as in A. Kinyii). 



Amphisboena innocens, Weinla/nd, Abhandl, Senckenberg.

Hab. San Domingo. 



Understood to have been previously described (Zool. Pec. 

 1865, p. 14!»)- Dr. D. F. Weinland does not characterize, 

 but gives a long description, with the following observa- 

 tions. 



The species is allied to A. emca, but differs in the fol- 

 lowing points: — 1, there are 212 verticilli between the 

 corner of the mouth and vent (226-229 in A. cam) ; 2, 

 the scutella are oblong, and not square as in A. coeca ; 

 3, there is no trace of a median dorsal groove as in A. 

 cceca.
