caught; the other was secured at Sandy Point, with the much more 
abundant species DM. acutifrons. In the original description JZ. australis is 
said to appear rather more slender than I. gludinosa, hardly differing other- 
wise unless it be that the tail appears somewhat sharper. The colors are 
given as those of an earthworm but more leaden on the upper portions, 
yellowish on the ventral surface, and purplish on the head. The specimens 
at hand agree with this, before the removal of the slimy covering, but after 
it has been rubbed off the color is dark brown on the back and white from 
snout to caudal along the median line of the belly. The white streak some- 
times is continued around anal and dorsal fins. In the two forms from 
Sandy Point the coloration is not greatly different but they are readily 
distinguished by other features. J/. australis is the more slender; it has 
from ten to eleven teeth in each series, the anterior two of each being 
confluent at their bases ; it has eighty to one hundred rays in the dorsal fin, 
and forty-five to forty-nine rays in the anal; there are twenty-eight to 
thirty-two pectoral pores, sixty-two to sixty-eight abdominal, and eleven to 
twelve caudal, on each side ; and the labrum is short and blunt or rounded,

This species is more slender and has a greater number of teeth and a 
larger number of pores than JZ. glutinosa. ‘The narial barbels are short and 
about equal in length; the labrum is short, blunt and rounded, resembling 
a small papilla or tubercle more than a barbel. The most common formula 
of the teeth has nine in each upper series, sometimes ten, rarely eight, and 
ten or nine in each lower, the anterior two of each series being confluent in 
their bases. On one specimen the dorsal has one hundred and _ twenty- 
four rays, on another one hundred and six. The number of rays in the 
anal fin ranges from forty-nine to fifty-four. There are from twenty-seven 
to thirty-one pectoral pores, from sixty-two to seventy abdominal, and
