Covered by large reticulations formed by white lines. Anterior 

 nostril tubes white and very short. Skin of the snout roughened 

 by small elevations. 



Nasal teeth, 12 ; nniserial, subulate, very acute, not tall. Three 

 teeth on the mesial line of the disk, the posterior one being the 

 tallest in the mouth, thickish at the base, and very acute. Vome- 

 rine teeth uniserial, short, acute. Palatine teeth, 10 in the outer 

 series, more compressed than the nasal ones, very acute and reflex, 

 forming a slightly-arched row; inner row of 2 taller ones at the fore 

 end of the hone. Eacli limb of the mandible is armed anteriorly 

 by 3 tall teeth, like the nasal ones, the second beiug the stoutest 

 and tallest, and in the same line, by 14 lateral teeth, which are 

 subulate and reflex, the foremost being smaller than the rest. The 

 mandible is slightly concave or recurved. 



This Murana has a different form from cancellata, a more obtuse 

 snout, a full and not concave profile, a shorter gape, smaller eye, 

 lower dorsal fin, and difl^erent colour, with fewer and larger meshes 

 formed by the white lines. The meshes are much less numerous 

 than those oi favaginea. The dorsal commences before the gill- 

 opening, and the vent is about one-fiftieth of the whole length 

 before the middle of the fish. The posterior openings are not 

 tubular. 



One specimen exists in the Museum of Haslar Hospital, and 

 another was presented to the British Museum by the College of 

 Surgeons. They are supposed to have come from the southern 

 seas, but the place of capture of either is unknown. [Richardson)
