MEMOIRS OF THE CARNEGIE MUSEUM. 



Family AMIID^. 



Genus Megalurus Agassiz. 



32. Megalurus lepidotus Agassiz. (Plate LXX, fig. 3.) 



(For synonymy cf. A. S. Woodward, Cat. Foss. Fishes Brit. Mus., Pt. Ill, p. 36.) 

 Only two examples of this early Amioid species are listed in Dr. Smith Wood- 

 ward's Catalog as belonging to the British Museum. The Carnegie Institute is 

 fortunate in possessing a number of well-preserved specimens, catalogued as follows : 

 4732, 4767, 4768, 4769, 4812, and 4862. The first four are in counterpart. 



33. Megalurus elegantissimus Wagner. (Plate LXX, fig. 2.) 



(For synonymy cf. A. S. Woodward, Cat. Foss. Fishes Brit. Mus., Pt. Ill, p. 365.) 

 The following numbered examples in the Carnegie Museum are referable to 

 this species: 693, 4854. 



Family PACHYCORMIDJ^.. 



Genus Sauropsis Agassiz. 



34. Sauropsis longimanus Agassiz. 



(For synonymy cf. A. S. Woodward, Cat. Foss. Fishes Brit. Mus., Pt. Ill, p. 375.) 

 This is an extremely rare form, occurring, so far as known, only in the Litho- 

 graphic Stone of Bavaria, though a closely related species, as yet undescribed, is 

 reported by A. Smith Woodward from the Oxfordian of Wiltshire. Neither the 

 Carnegie nor the British Museum possesses examples of the species. 



35. Sauropsis depressus, sp. nov. (Plate LX, fig. 3.) 



Type. — Nearly complete fish; Carnegie Museum Cat. No. 4766 + 4766a. 



Form of body slender and elongate, the length of head with opercular apparatus 

 considerably exceeding the maximum depth of trunk. Pelvic fins arising midway 

 between the pectorals and the anal; dorsal fin arising opposite the low fringe-like 

 posterior portion of the much extended anal, and consisting of comparatively few 

 rays; the anterior rays of the dorsal and anal equal in elevation, but rapidly de- 

 creasing posteriorly. Other characters similar to those of the type species. 



The holotype of this extremely slender species is a well preserved skeleton 

 having a total length of about 32 cm., in which the trunk is exhibited from the 

 lateral, and the head, which is reflexed, from the ventro-lateral aspect. It is in 

 counterpart, and the skeletal structure can be studied in its entirety by combining 

 both halves. In the tyi:)c specimen of S. longimanus figured by Agassiz the head
