1056 REPORT OF NATIONAL MUSEUM, 1898. 



tlie species of the HJ. sirtnlis group, but is quite different from any 

 of the forms which I have included in that protean species. The 

 tail is longer, as I find out of ninety-seven specimens of the latter 

 which I have measured but five have the tail as long as in the speci- 

 men of E. vidua with the shortest tail and none with so long a tail as 

 the other. The eight superior labials distinguishes it from all but 

 four specimens of the ninety-seven, and in some of these the additional 

 labial is an intercalation. Two of the four specimens come from the 

 same locality, namely, San Francisco. The compressed body is seen 

 in a few specimens of the E. NirtaU.s pickeringii, also from the Pacific 

 region, but not in any other forms. In some of these the stripes dis- 

 api)ear, but all together, and not the lateral only, leaving a well- 

 deve]oi)ed dorsal. The coloration is a curious parallel of the " y/</«a" 

 form of the E. leptocephala^ which it closely resembles. The superior 

 labials of the latter are different in being lighter and with black borders, 

 and the throat is whitish and the muzzle brown. 



While this form has these points of connection with certain extremes 

 of variation of the E. sirtalis, it agrees with none of them, and may be 

 regarded as a species until more definite points of connection are found.

But one specimen of this species has yet been obtained. It is small, 

 but not young, and it belongs to the group of which E. sirtaJis and E. 

 leptocephdla are members. It resembles both these species, but differs 

 in important particulars. The labial plates are six above and eight 

 below, instead of seven above and ten below. The head is not distinct 

 from the neck, resembling in this respect the Tropidodonium lineatuin. 

 The parietal scuta are convex in outline and not contracted posteriorly. 

 The head plates are otherwise as in those species, including oculars 1-3, 

 temporals 1-U; and postgeneials longer than ])regeneials. Scalesin nine 

 teen series, all keeled except the inferior row, which has a trace of a 

 keel. Gastrosteges, one hundred and thirty-two; anal, one; urosteges,
