Head li in trunk; trunk 2 in tail. D. 17; P. IS. Rings 11+39, 
each of them essentiall}' siniikir to its neighbors, none of them espe-

to knol) above gill opening. P]ye about 3 in snout; supraorbital spine 
simple, not divided; no spine on median line before eye. Depth of 
body at tenth ring 1^ times snout. Dorsal on 3i rings (l^+i^). Egg 
pouch on 7 rings. Coronet low, about as high as eye, slanting })ack-

presented by the Imperial University, and collected by Professor 
Mitsukuri. 
This is evidently the Ilippocainpus lonxjiroatrlH of Schlegel, but 
not of Cuvier, whose species is based on a figure of Willughby. It 
is close to //. kuda., but diti'ers, at least, in the greater number of 
rings and in their uniformity. (Named for Prof. Vernon Lyman 
Kellogg, of Stanford University.)
