much of the rostrum, the head and most of the pectoral fins. 

 There is likewise the trunk of a species of the genus present. 

 These specimens show that Sclerorhynchus belongs to the Pris- 

 tidee, and further, that at that far away day the sawfishes 

 resembled closely those of our time, except in the mode of 

 attachment of their rostral teeth. Between that time and the 

 Eocene, these modified shagreen scales found deeper and deeper 

 lodgement in the cartilages of the rostrum, attained greater size, 

 and became the efficient weapons that we find them to-day. 



The new Sclerorhynchus which is represented by the rostrum 

 alone has been called S. sentus, because on one flat side of the 

 rostrum there are two rows of short spines. The species repre- 

 sented by the complete rostrum has been named S. sohmoms, 

 in recognition of the interest of the great Israelitish king in 

 natural history (i Kings, iv, 33). The third species is to be 

 known as 5. Jiiram, in honor of the friend and ally of Solomon. 



Of the genus Rhinobatus three species have already been 

 described from Sahel Alma and one from Hakel. A new one, 

 R. eretes, is found in the collection from Hajula. Likewise a 

 new ray comes form Hajula, and this has been named Raja 

 whitfieldi, in honor of Prof. R. F 

 Museum. It is surprising to obsei

beds but few representatives of the old families of the Jurassic. 

 None has been obtained at Sahel Alma, and this speaks for the 

 later time of these beds. From Hakel there have been known 

 four species of pyenodonts ; and now from Hajula there is 

 secured a new one, Coccodus insignis. It is represented by 

 many specimens, some of them quite perfect ; and is character- 

 ized by having a short and compressed occipital spine. It like- 

 wise presents clear evidences of pectoral and ventral fins. Hakel 

 furnishes a new and strange fish which possibly belongs to the 

 Belonorhynchida;, and which has been named Stcnoprotomc
