caught ; the other was secured at Sandy Point, with the much more 

 abundant species M. acidifrons. In the original description M. austndis is 

 said to appear rather more slender than M. glutinosa, 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. M. 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,

 The teeth are more slender and longer than those of 31. acutifrons.

This species is more slender and has a greater number of teeth and a 

 larger number of pores than M. 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 

 ton 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 ninnber of rays in the 

 anal fin ranges from forty-nine to fifty-four. There are from twenty-seven 

 to thirty-one j)ectoral pores, from sixty-two to seventy abdominal, and
