1 Pseudocaudal developed. 



(spinosus, in reference to the very spiny scales.) 



64. LIONURUS INFRANUDIS, new species. 



Type-specimen.— Oat. No. 82669, U.S.N.M.; 203 mm. long to end 

 of pseudocaudal, 50 mm. to anus; dredged at Albatross station 

 5586, off Sibuko Bay, Borneo (lat. 4° 06' 50" N.; long. 118° 47' 20" 

 E.) : depth, 347 fathoms; bottom temperature, 44° F. 



Fin-rays — first dorsal, II, 12 ; ventrals, 11 ; pectorals, 21. 



The body is rather slender, the dorsal contour sloping forward in 

 a gently convex curve from the elevated origin of the first dorsal fin 

 to the subconic snout. The horizontal projection of the snout beyond 

 the front of the premaxillaries is equal to the length of the pupil; 

 the preocular length, about 0.2 longer than the preoral length, and 

 equal to the height of the orbit, is contained 3.33 times in the head. 

 The orbit is not quite round, the vertical diameter being a little 

 greater than its horizontal length, which is contained 1.55 times 

 in the postorbital, or 3.6 times in the entire length of the head. The 

 margin and the ridge of the preopercle are not sharply produced 

 backward at the angle, above which they are vertical. The least 

 width of the narrow interorbital space is contained 1.4 times in the 

 orbit, or 2.2 times in the postorbital ; the suborbital is narrower than 

 the pupil. The length of the upper jaw, which extends backward 

 to below the posterior half of the pupil, is contained 3.25 times in
