Family XXXVIII. SOLENOSTOMlDiE. 
Body compressed; tail very short; snout long, compressed, all parts covered with thin skin, 
below which is the dermal skeleton with star-like ossifications; spinous dorsal short; soft dorsal and 
anal long, with elevated base; caudal long; ventrals close together, inserted opposite spinous dorsal, 
each of 7 rays; the fins free in the male, in the female adnate to the body, forming a large pouch for 
the reception of the eggs; branchiostegals 4, very thin; intestinal canal simple. Singular fishes of the 
East Indies, constituting 1 genus. 
Genus 65. SOLENOSTOMUS Lacdpede. 
Characters of the genus included above. 
Solenostomus Lacepede, Hist. Nat. Poiss., V, 360, 1803 {paradoxus). 
78. Solenostomus cyanopterus Bleeker. Fig. 35. 
Head 2.2 in length; depth 5; D. v-20; P. 27; V. 7; A. 19; CJ 15; depth of snout at middle 4.5 
in its length; eye 6.25 in snout; dorsal spines 2 in head; ventral equal to snout or a little mere; caudal 
a little shorter than head; caudal peduncle shorter than base of second dorsal. 
Color pink, with small black dots like ink specks scattered over head and upper part of body; 
eye red; fins pale, the spinous dorsal with 2 long black ocelli (said to be dark blue in life) on mem¬ 
branes of first and second spines; besides black dots, caudal with small inky spots like those on body, 
but more elongate, several of them drawn out into lines. The above description is taken from Jordan 
and Snyder’s Japanese specimen. The only Hawaiian reference is that given by Bleeker. It, is doubtful 
if the species really occurs in these islands.
