dorsal, and the caudal and anal are bordered with the 
same. 
I have seen two specimens, the longest of which measures 
five inches, but Mr. Waterhouse tells me that he has one 
almost twice that size. 
The fish on which this genus is established must be very 
nearly allied to Richardson's Aploactis Milesii (Proc. Zool. Soc. 
1850, p. 60 - Pisces, pi. 1, figs. ], 2, and repeated Ann. and 
Mag. Nat. Hist., 1851, vol. ii., p. 275—277). But the 
presence of teeth on the palatine bones and the difference in 
the composition of the fins (D ji A. 12) obliges me to con- 
sider it as distinct. In all cases it cannot enter the genus 
Aploactis, on account of the characters I have just mentioned, 
and if it was found that some mistakes have taken place in 
Richardson's description, which is possible as he had only 
seen a dried specimen, and that the two sorts are identical, then 
the specific name would be Milesii Richard. 
I have named this sort in honor of the learned Director of 
the Adelaide Botanical Gardens. 
CHIEONECTES FILAMENTOSUS. 
Body rather globulous : its height is two and one-third 
times in the total length, and the breadth five-sixths of its 
height. The upper profile is very gibbous in front. 
The fish is smooth but entirely covered with long fringes 
measuring about half an inch • the mouth is broad ; the lips 
have strong tubercles. The upper teeth are small and 
conical, the lower are also on several series ; the most internal 
of which are long, sharp, and directed on several rows placed 
inwards. Inside the mouth, there is also on each side a 
bunch of teeth; there is on the head a long thin spine 
supporting six or seven long cutaneous tentacles, some simple 
and some bifide ; on each side of this spine is inserted a 
slender filiform, and rather long tentacle, which terminates 
by two large, fleshy, pointed appendices. This fleshy part has 
more than one-half the length of the filiform one • the eye is 
pediculated and surrounded by tentacles. 
Behind the spine of the head is another, on the back ; it is
