found in the Craddock bone-bed near Seymour, Texas. One 

 of the most striking features of these two skulls is the absence 

 of the parasphenoid rostrum between the pterygoid openings. 

 The author failed to find a pineal foramen, though this is 

 described and figured in the memoir on Diplocaulus by Prof. 

 Douthitt already alluded to in this review. 



Mr. L. Hussakof {Bull. Amer. Mus. Nat. Hist. vol. xxvii. 

 pp. 761-7, November 191 7) describes two new species of 

 fossil fishes, collected by the American Museum Congo Expedi- 

 tion. The first of these is a species of Lepidotus new to science 

 (L. congolensis) ; based on fragments of the jaws and scales. 

 It was obtained from the Mission of St. Gabriel, situated on 

 the right bank of the Congo, a few miles above Stanleyville ; 

 a station not previously known as a locality for fossils. The 

 second species was obtained from Landana, some sixty-five 

 miles north of the mouth of the Congo. It is undoubtedly a 

 ray, and is provisionally referred to the genus Rhinoptera. 

 Unfortunately no more than a single tooth was obtained, and 

 it would seem that it may possibly represent an immature 

 specimen of Myliobatis, of which one species has already been 

 recorded. The formation from which this was obtained is 

 correlated, approximately, with the Montien stage of Northern 

 France and Belgium.
