COAST. 
By J. Douglas Ogilby. 
Centrina bruniensis, sp. nov. 
Centrina bruniensis , Morton (in lit.) 
Body oblong, with the back and sides rounded, and the belly 
flattened. Head small and strongly depressed, its breadth equal 
to the distance between the tip of the snout and the spiracle : 
snout short and obtuse, the distance between its tip and the 
nearest point of the mouth less than that between the same and 
the anterior margin of the eye. Nostrils equidistant from the eye 
and the extremity of the snout. Eye large, with a strong bony 
supraorbital ridge, situated midway between the tip of the snout 
and the anterior gill-opening. Spiracles large, opening behind the 
upper half of the eye, with a moderate intervening space. Mouth 
small and transverse, with the lateral groove very broad and 
deep. Upper jaw with a patch of small, conical, curved teeth 
anteriorly, consisting of about four irregular rows ; a single 
series of much larger, erect, compressed, minutely serrated, scalp- 
riform teeth in the lower jaw. Gill-openings small, the posterior 
one pierced immediately in front of the base of the pectoral fin. 
The first dorsal commences above the middle gill-opening, and 
rises by a continuous and equal gradation to the spine, its outer 
margin being straight ; behind the spine the rise is much more 
abrupt, and the contour is slightly convex with the tip rounded ; 
the posterior margin is deeply concave ; the height of tfle fin 
beneath its extremity is equal to the distance between the anterior 
gill-opening and the tip of the snout, that of the spine equal to 
the head in front of the spiracle ; the spine is situated in the 
anterior portion of the last fourth of the base of the fin, is perfectly
