FISHES OP CEARA, BRAZIL JORDAN AND BRANNKR 23 



Of this small species we have two fragments (i8, 19, Rocha 

 Collection) fram Ceara. The best of these (No. 18) shows a crushed 

 head and part of the side of the body. Scales in about 15 rows above 

 lateral line and 15 below. It seems to differ from Rliacolepis hiiccalis 

 in the greater depth and compression of the body, the head being 

 rather abruptly reduced in depth. Three orbital plates subequal, 

 parallel ; distance from gill opening to ventrals less than length of 

 head. Opercle more than twice as large as subopercle, the suture 

 very oblique ; nuchal plate distinct. A trace of lateral line. The 

 other specimen shows mainly the scales on the side anteriorly. Our 

 specimens, however, add nothing to the account given by Woodward, 

 and it may be possible tha't these specimens are simply Rliacolepis 

 buccalis crushed flat. 



Genus ENNELES Jordan and Branner, new genus 



Allied to Elopopsis (Ileckel, Denkschr. Akad. Wiss. Wien., xi, 

 1856, p. 251; type, Elopopsis fenzli Heckel). Among the Blopidcc 

 this genus is distinguished by the very wide-set teeth, and by the 

 wide gape which extends beyond the eye. From the type of the 

 genus Elopopsis our Brazilian species differs in having a series of 

 short, compressed teeth in the posterior part of the mandible, and the 

 teeth on maxillary sharp and equal in length. 



Pachyrhicodns, Agassiz, another Cretaceous genus with similarly 

 large teeth, is closely related, but in that genus the teeth are closer 

 set and more uniform. 



9. ENNELES AUDAX Jordan and Branner. new species 



Plate VII 



Type a skull six inches in length, from Ceara ( No. 22, Rocha Col- 

 lection). With this is a partial counterpart showing the anterior 

 part of the head without the lower jaw, the teeth of the maxillary 

 being well preserved. 



Depth of head if in its length. Snout rather pointed, longer than 

 eye, 3^ in head; eye about 51^. Gape of mouth extending far be- 

 yond eye, its length about 1% in head; supraoccipital crest somewhat 

 elevated ; branchiostegals numerous, 10 behind the end of the gular 

 plate. Gular plate well preserved, very large, narrowly fan-shaped, 

 its length nearly half that of head, its breadth at posterior end nearly 

 half its length; mandible very strong, about if in length of head; 

 jaws even in front. 



Teeth large, robust, wide-set, broadened at base and bluntly and 

 rather abruptly narrowed at tip, the free portion of the longest about
