The scleral structures are so \'ery like those of L lu.iiii tliat the fonn, 

 if roughly or carelessly exaiiiinecl, n!ii;ht be included witiiiii that species. 

 The 1) id>' is elongate, and shows in .s Jinc measure a cy!i.i<!ri;a! appearance 

 but is somen lilt llattencd laterally ; the greatest 

 dei)th is a liLtlc less than o:ie-si\tii the length 

 total. Wnen viewed laterally, the back is near- 

 ly- str.iight from the occiput to the .interior 

 origin of the dorsd fin. The belly is gently 

 arched, the highest part beiiig some distance 

 anterior to the ventral fins wiiere tjie body is 

 of the greatest depth. The eaiidal peduncle is 

 rather ileep, measuring a little less than half 

 the greatest dei):h of the botly { h'ig. I.) 



The lenght of the head goes about three 

 and a half in the length toted, and well repre- 

 sents die characteristic feature of the T.ncäidae 

 i.i h:uing a flattened back and a spatulate snout, 

 the length of which in turn is from 39 ^:o to 

 .41 '?ö of that of the head. Wiien \'ie\> ed. from 

 above, the snoui rewals itself as a semielliijse like 

 other i)ikes ; its width is two third.s the length. 

 The Ijwer jaw projects a little bevond the upper. 

 The eyes lie just in front of the middle of the 

 Jieatl close to its upper nvargin, aiid their 

 longest diameter is from 9,'l9 to 1 1/45 the length 

 of the snout, and from 9 '65 to I 10 that of the 

 head. The inlerorbital space is twice as wide 

 as the eyes, well agreei.ig with the description 

 of Dybou-ski.''' The maxillary is a little shorter 



than half the length of the head, extending
