fin. Where the incrustation of scales remains there is seen 

 a number of very distinct narrow, longitudinal, whitish lines 

 along the body. These probably indicate rows of scales. I 

 count about lo of these lines below the vertebral column, and 

 apparently 5 or 6 above it. Possibly this species was longi- 

 tudinally striped. No additional information regarding the 

 scales is to be obtained.

There are several specimens of eels from Hajula which are 

 referred to this supposed new species. None of these are 

 complete fishes, more or less of the caudal region being miss- 

 ing in all of them. No. 4515a (3654) is regarded as the type 

 (PI. XXX VI, Fig. i). Of this individual, perhaps about 25 

 mm. of the extremity of the tail is gone. The remainder of the 

 animal is well preserved. Anteriorly the head and trunk are 

 viewed from above; from just in front of the anal fin back- 

 ward the fish lies on its side. This species is closely related to 

 U. avus, described by Dr. A. S. Woodward from the Upper 

 Cretaceous of Sahel Alma (Cat. Foss. Fishes, IV, p. 337, pi. 

 xviii, figs. I, 2), and there are few characters by means of 

 which it may be distinguished. However, it appears that the 

 part of the trunk which lies in front of the anal fin has a 

 greater number of vertebrae, and it is longer in proportion to 

 the length of the head than in U. avus. The latter is stated 

 to have about 35 vertebrae in front of the anal, whereas U. 

 germanus possesses over 40. This portion of the trunk is also 

 about 5 mm. longer than that of U. avus relatively to the 

 length of the head. 



For these reasons I regard the Hajula specimens as form- 

 ing a distinct species.
