 mm. Localitj!-, Tanegashima, Japan. 



(yoshi, a Japanese word meaning a reed.) 



ICHTHYOCAMPUS NOX, new species. 



Head 8.2 in length to base of caudal; depth 18; depth caudal 

 peduncle 7.5 in head ; snout 2.5 ; eye 5 ; D. 20 ; A. 3 ; rings 16-}-31. 



Snout with a strong median keel which abruptly ends on interor- 

 bital area; a lateral one of about one-half the height of median keel 

 extending obliqueh^ from tip of snout to eye; a third extending 

 alongside of snout to opercle; another on lower edge of snout; oper- 

 cle with a keel on anterior third, from which faint lilies radiate ; su- 

 praorbital keels converging toward a short median ridge behind. 

 Body with a median ventral ridge and 3 lateral ones. Tail square 

 in cross section, except on 3 anterior rings over which the median of 

 the lateral ridges extends. Plates of body without spinous angles; 

 those of tail with incipient spines on upper angles 



Dorsal extending over 5.5 rings, 5 of which belong with the tail. 

 Caudal equal in length to diameter of eye. Pectoral slightly longer. 



Color of preserved specimen almost black ; a narrow stripe, scarcely 

 visible, extending along each flat surface; caudal narrowly edged 

 with white. 



Described from the type, a female 51 nnn. long, from Naha, 

 Okinawa.

MICROPHIS OCELLATUS, new species. 



Head 5.7 in length to base of caudal ; depth 1.7 in head ; depth 

 caudal peduncle 7 ; diameter eye 6 ; length snout 2.5 ; D. 30. A. 5 ; 

 rings 19+18. 



Body of about equal dei^th from occiput to tail where it abruptly 

 grows smaller, the outlines of the tail gradually sloping to the caudal 

 peduncle. Snout perceptibly curved upward ; narrow, the width 

 slightly less than diameter of orbit; rounded anteriorly. Nostrils 

 with low rims. Head with ridges as follows : one above eye, having 

 its origin on tip of snout, curves outAvard as it pas.ses back, abruptly 

 bends inward and increases in height on reaching nostrils, then bends 

 outward and curves downward behind the eye and extends to upper 

 edge of opercle ; one on occiput ; a central, oblique one on opercle with 

 lesser ridges radiating from it : 3 on each side of snout. Each body 

 ring with a median dorsal and ventral keel, except where displaced 

 by ogg-pouch or fin ; 5 lateral keels, the fourth row of which, count- 

 ing from above, disapj^ears near vent ; the third and fifth rows unite 

 just posterior to vent; caudal rings each with a dorsal, ventral, and
