orbital region convex, its width 3|- in the head. Maxillary extending 
to the vertical from the anterior border of the pupil. Space between 
origin of dorsal and root of caudal If in its distance from the tip of 
the snout ; length of dorsal tin •§ of its height : adipose dorsal 
inserted much nearer to the caudal than to the rayed dorsal and' 
wholly behind the anal. Anal fin commencing a little behind the 
origin of the dorsal and much nearer to the origin of the ventral 
than to the caudal, as high as and 1^ time as long as the rayed 
dorsal. Caudal emarginate, the middle rays f of the outer, which 
are 5| in the length of the body : caudal peduncle slender, its least 
depth 2-f in the depth of the body. Pectoral rounded, 1^ in the 
head. Yentral inserted midway between the tip of the snout and 
the last anal ray, its length 1^ in the head. Yellowish brown, with 
an ill-defined paler longitudinal band from the eye to the middle of 
the tail ; distal half of tail with a dark median streak, which expands 
posteriorly to form a dusky blotch at the base of the caudal ; upper 
surface densely powdered with blackish dots ; opercles with larger 
dots ; a series of similar dots at the bases of the rayed dorsal and 
anal. [Named for William Edward Weatherill, its collector]. 
Type in the Queensland State Museum. 
Total length 57 millimeters. 
Streams near Brisbaue. 
* Differs from Aplochiton sealii Johnston,* in the much deeper 
body, the compressed and longer head, the shorter snout, larger eye,

THORN-TAILED PIPE-FISH. 
Osseous rings 16 + 30. Body heptagonal and rather stout, its 
width If in its depth, which is less than the postorbital portion of 
the head. Frontal region of head obliquely linear ; length of head 
3f in the preanal length, which is If in the length of the tail. 
Snout curved upwards anteriorly, with a moderate keel above and 
below, half as long as the rest of the head. Occipito-nuchal carina 
originating on a level with the posterior border of the orbits and 
terminating at the end of the 1st. body ring ; it is moderately deve- 
loped and divided by notches into three subequal sections ; supra-
