Under the appellations of M. hrmiliensis and jounctata, Castel- 

 neau found Brazilian specimens in the Paris Museum whicli are 

 besprinkled with yellowish dots of the size of pins' heads. I con- 

 sider them to be a local variety of the common M. helena. (lump.) 



109. MuE^NA VEEMICULARIS. 



Muraena vermicularis, Peters. 



In the form of the teeth, this species resembles helenn ; but its 

 snout is more obtuse, and its head less compressed. The dorsal 

 originates directly over the gills, and the anus is in the middle of 

 the length, or a little before it, while the eye is over the middle of 

 the gape. The dorsal exceeds the anal in depth, and is about 

 equal to one-fifth of the height of the body. Colour, green ; on 

 the back, brown, with dark reticular marbled markings, which ex- 

 tend over the pectorals. Ground colour of the snout and chin, 

 white, with dark-green spots and marbling. 



Total length, 1044 in. Diameter of the eye, 0'127 in. From 

 the tip of the snout to the corner of the mouth, 047 in. To 

 the gill-opening, 1-3S in. To the dorsal, 1'46 in. To the anus, 

 5-lCin.
