JORDAN AND THOMPSON: FISHES OBTAINED IN JAPAN IN 1911. 297 
Color in alcohol dark brown, five indistinct cross-bars of darker brown as wide 
or wider than eye on upper part of body, first under spinous dorsal second under 
insertion of second, last on middle of caudal peduncle; between these cross-bars 
indefinite reticulations of darker brown; cheeks, side of snout, and opercular 
membranes with narrow sinuous lines margined differently with white, five or six 
present on lower membrane of eye; a dark blotch above and behind pre-opercular 
spine; spinous dorsal without striking coloration; indefinite large whitish spots in 
reticulations of darker color present; soft dorsal with two rows of indefinite, fused 
spots throughout; one or more on first rays and two more on last; soft dorsal and 
upper half of caudal with three narrow lines of dark along margin; caudal with three 
cross-bars of dark, intervening lighter areas set with minute, oblong, sharply defined 
spots of brown, with lighter centers; some of these also found on last dorsal ray; 
anal spots uniformly dark brown; pectoral with four or five irregular rows of these 
spots, on basal half ocellated with white, and a distal cross-stripe of white on upper 
half; ventrals uniformly dark, save for occasional darker spots on basal portion. 
The peculiar form of the maxillary, the fold of skin along the side of the body, 
the opercular flap, and many-hooked spine of the pre-opercle, distinguishes this new 
genus, Calymmichthys from all other Japanese Callionymide. The opercular flap 
is found in Synchiropus opercularis (Cuvier and Valenciennes) from India. The 
hooked spine is found in Calliurichthys but in that genus these hooks are so small 
as to be called serrations. 
Family GOBIESOCID. 
335. Aspasma minimum (Déderlein). 
Misaki, No. 6076a. 
According to Tanaka (Journ. Coll. Sei., Tokyo, XX VIT; 1909, p. 25) Aspasma 
laticephalum Tanaka differs from this species in having several rows of villiform 
teeth. It then stands alone among Japanese species and is apparently referable 
rather to the European genus Mirbella Canestrini. 
The dorsal rays in A. minimum are 7, the anal 6. In A. ciconie we have D. 12; 
A. 8. In A. misakiwm, D. 14; A. 12. 
336. Aspasma misakium Tanaka. 
Misaki, No. 6128a. Longest specimen 5.8 cm. in length. 
A shade of pink still left in spirits. This species differs from A. ciconia in 
the lesser breadth, much smaller disk, and in the greater number of rays in the 
dorsal and anal fins, as well as in the character, given by Tanaka, of the shorter 
maxillary and coalescent vertical fins. Teeth in both jaws in one row.
