REPORT OF NATIONAL MUSEUM, 1898. 



number (fifteen) of scale rows, by the different distribution of the lat- 

 eral stripes. In Z. I. lateralis the yellow stripe is confined to the third 

 and fourth rows, and the dark baud below it covers the extremities of 

 the gastrosteges. lu the Z. tcvniatus the yellow stripe extends to the 

 fifth row of scales, and the inferior band only reaches to the middle of 

 the first row, not attaining the gastrosteges. In Z. schottii the supe- 

 rior lateral stripe is as in Z. I. lateralis, but the belly is dark and there 

 is a yellow stripe on the adjacent edges of the gastrosteges and first 

 row of scales. The head is unicolor and not spotted, as in the Z. I. later- 

 alis. The yellow temporal spot of both forms of the Z. lateralis is to 

 be noted as always absent from the allied species. The Z. semilinatus 

 agrees with the lateralis in the possession of seventeen rows of scales, 

 and the young is more fully striped than the adult. It may be dis- 

 tinguished at all ages by the arrangement of the lateral stripes and. 

 the uniform coloration of the head. The yellow stripe is, like that of 

 the Z. lateralis, on the third and fourth rows only, but the dark band 

 below it only occupies the adjacent parts of the second and third rows, 

 instead of extending to the gastrosteges. There is a yellow band on 

 the adjacent parts of the first and second rows which is absent in the 

 Z. lateralis, and there is a dark stripe on the adjacent part of the first 

 row and the gastrosteges, where the inferior yellow stripe is i^resent in 

 tlie Z.schottii. The belly is light, and not dark, as in the last-mentioned 

 species.
