hofen. The head is much crushed and abraded, but a few 
tubercles remain upon the cranial roof and the mouth is 
opened to display the characteristic teeth. The anal and 
caudal fins are especially well preserved, the latter ex¬ 
hibiting its gently excavated posterior margin.

Type . Scale; Museum of Soleure, Switzerland. 
An imperfectly known species of moderate size. Teeth short and 
stout and smooth, the majority oval in outline and with a well- 
defined median coronal tubercle or apex ; splenial teeth apparently 
in more than three concentric series. Scales as in L. polliatus. 
The dentition described and figured as mandibular by Fricke 
seems to be more probably pterygo-palatine and exhibits four 
longitudinal series of teeth. ^
