22 NEW PEDICULATE FISHES 
clouded with violet ; anal fin similar to the soft dorsal, but 
crossed by four dark bars, the basal one continuous, the 
others interrupted ; caudal rays with black and yellow rings, 
the membrane uniformly hyaline ; posterior half of the outer 
edge of the pseudobrachium and the pectoral rays black- 
ish ; ventral rays similar with lighter tips. (Named for 
Dr. A. Graham Butler, its discoverer). 
Type in the Queensland Museum, Brisbane 
Length to tip of middle caudal ray 93 millimeters. 
Distribution : Port Curtis, Queensland. 
Writing of this species Dr. Graham Butler informs 
me :—‘‘ The specimen in question was caught by the local 
fishermen. while netting among coral and seaweed for 
Trumpeter at ‘North End’, port Curtis Harbour. They 
had not seen one like it before, so it is evidently uncommon 
Mere... 4a The color was a brilliant orange.’’ Within the 
few days which elapsed between its capture and my receipt 
of it, the brilliant orange had faded to a dead white, with 
here and there a roseate tinge. 
The most noticeable character in this fish is of course 
the enormous elongation of the carpal bones, which gives 
to the pectoral limb very much the appearance of the fore- 
leg of a frog, and like it is cabable of moving easily upwards 
or downwards, but can only move forwards to a right angle 
with the body from the joint which unites it to the pectoral 
arch, the want of elasticity in the axillary membrane not 
permitting of a further movement in that direction. The 
second joint, however, allows of the pectoral rays being laid 
directly forwards alongside of the proximal actinosts. The 
fin itself is narrow, and resembles more the claws of a bird 
than the rays of a fish.
