829. MACROSTOMA MARGARITIFERUM (Goode & Bean). 



Head 4; depth 5; eye moderate, about 4 in head. D. 16; A. 14. Least 

 height of tail i of greatest height of body. Snout very short, compressed 

 into a keel on its upper edge, its length scarcely more than i diameter 

 of the eye. Gill rakers 9 or 10 above the angle, about 16 below, the 

 longest about f the diameter of eye. Intermaxillary reaching almost 

 to angle of preoperculum. Space between eye and hinder edge of pre- 

 operculum much less than diameter of the eye. Origin of dorsal much 

 nearer tip of snout than root of caudal, about over ninth scale of lateral 

 line, and in same vertical with origin of ventral ; length of dorsal base 

 nearly i of total (without caudal) ; the ventral does not quite reach to 

 origin of anal ; pectoral very short, its length only -J- that of head ; no 

 adipose dorsal ; anal origin under eighteenth scale of lateral line ; base 

 of fin as long as head without snout ; caudal moderately forked. On 

 top of the caudal peduncle a long, linear mirror, nearly i as long as head, 

 its width about i of its length. Several large phosphorescent spots on 

 inner edge of mandible, a large one near angle of preoperculum. 



Mediolaterals 3, in a curved, sub vertical line. Posterolaterals 2, under 

 soft dorsal. Superanals 9 + 7. Precaudals 2 + 2, the last below end of 

 lateral line. Grand Banks of Newfoundland ; known from two speci- 

 mens. (Goode & Bean.) (margaritifer, bearing pearls.)

830. MACROSTOMA ANGUSTIDENS, Risso. 

 (PRICK FISH ; MAIRE D'AMPLORA.) 



Head 4 ; depth 5* ; eye moderate, 4f in head. D. 21 to 24 ; A. 17 or 18. 

 Caudal spots 4, 2 horizontally placed, 2 at base of caudal rays; 

 posterolateral spots 2 or 3 ; anal spots about 8 + 7 ; supra-anal spots 3, not 

 quite in line; ventral spots 5 or 6; a white or luminous spot on back of 

 tail. Preopercle very oblique. Body elongate, the caudal peduncle not 

 very slender. Head moderate, snout very short, low, but bluntish at tip ; 

 chin prominent; mouth not very oblique. Dorsal very high, anal long; 

 pectoral slender, narrow, placed low, with 12 rays, not reaching ventrals. 

 A luminous gland above and one below tail. Atlantic and Indian Oceans, 

 Norway and Greenland. (Liitken; here described from Mediterranean 

 examples.) It is not unlikely that several species are confounded under 

 this name. According to Goode & Bean, the original elongatum may be the 

 one called by them quercinus. (angustus, narrow; dens, tooth.) (Eu.)
