OF AUSTRALIA. 145 
rat her long, sharp, and pointed ; a single conical and rather 
notched spine in front of the coronet; this with its 
terminal five points well marked ; eleven body rings ; the 
part supporting the dorsal very little higher than the back. 
In a dried state the fish is of a light greyish yellow, covered 
with more obscure brown, irregular, marbled spots. 
Length of specimen, three inches in a straight line. 
HIPPOCAMPUS SUBELONGATUS. 
Dorsal fin with eighteen rays standing on three body rings ; 
body rather elongate, the broadest part not being more than 
one-third thicker than the narrowest ; snout up to the anterior 
edge of the eye longer than the other part of the head ; 
tubercules moderately acute ; a short, thin, rather rounded 
ridge in front of the eyes ; supraorbital spine broad, arched, 
and rather notched; a single short, blunt, and notched 
spine in front of the coronet ; this rather elevated, directed 
very obliquely, and ended by five well marked but blunt 
spines ; eleven body rings. 
Colour of dried specimen yellow, with transverse brown 
narrow bands on the snout. 
Length, in a straight line, four inches and three-eighths.

Skin covered with small spines, truncated at their extremity ; 
body high ; its height being only contained a little over twice 
in its total length ; the upper profile of the head is considerably 
concave ; the portion of the back profile, extending from the 
spinous dorsal to the base of the soft one, is straight or rather
