1090 REPORT OF NATIONAL MUSEUM, 1898. 



rior labials; geneials elongate, the pair subequal. The head is an elon- 

 gate oval, narrowed anteriorly, and quite distinct from the neck. Tlie 

 tail is one-fourth the total length. Scales in twenty-one longitudinal 

 rows, all strongl}^ keeled except the lirst and second on each side; all 

 poreless. Gastrosteges one hundred and seventy - seven ; urosteges 

 entire, four; divided, thirty-three. 



General color above light brown, olive sliaded on the iiead. The 

 anterior half of the body is marked with six rows of small alternating 

 bright rufous or orange spots, each of which occupies one, and some- 

 times an adjoining scale. They stand on the first and second, the fifth, 

 and on the eighth rows, respectively. On the posterior third of the 

 length they are wanting, and are indistinct posterior to the middle of 

 the length. The lower surfaces are pale brownish gray; the base of 

 each gastrostege with blackish markings. Labial plates light;' head 

 without spots. There is an inferior preocular higher than long on one 

 side of this specimen. 



This species is nearly related to the I], multimaculata, and better 

 specimens may prove them to be identical. However, there is a con- 

 stant difference in the shape of the rostral plate, which has the form 

 usual in Eutcenia in the IJ. mnltimacnlata, while it is so peculiar in the 

 present species as to have given ground for its separation in a dis- 

 tinct genus. This plate is obliquely truncated laterally and produced 

 posteriorly at the middle of the posterior border, in the U. multimaculata; 

 while it is low and truncate posteriorly, having a transversely ovate 

 form in the E. rufopunctata. Its border is slightly free all round in 

 the latter, which it is not in the former; but this appearance may be a 

 result of drying, though I do not see exactly how it can have so arisen. 

 This species further differs from the E . multimav7ilata in thetwo superior 

 labials entering the orbit; in the rather more elongate internasals and 

 prefrontals; in the more posteriorly-produced loreal, and in the superior 

 labials, of which the third nearly enters the orbit. However, some speci- 

 mens of the E. multimaculata approach it in one or the other of these 

 respects, and the narrowness of the labials has been somewhat exag- 

 gerated by the partial drying to which the specimen has been subjected. 

 To the same cause may be ascribed some errors in the original figure 

 and description. Thus the nasal plates are not confluent, nor does the 

 loreal plate quite enter the orbit as has been stated.' The figure omits 

 the postocular plates, which were simply turned into the orbit by dry- 

 ing. The rostral plate is accurately represented.
