28 ZOOLOGY OF THE VOYAGE OF THE BEAGLE. 



than in the T. Hirundo. Two spines at the anterior angle of the eye ; but none at the posterior 

 angle, or on the temples. Suprascapular, opercular, and clavicular spines much as in the 

 T. Hirundo. Lateral line and whole body smooth, excepting the dorsal ridges, which are 

 strongly serrated. Dorsal spines as in the T. Hirundo ; second longest ; the first with a 

 series of obsolete granulations on its anterior edge. Pectorals not quite one-third of the entire 

 length : free rays incrassated in the middle, tapering towards the ends, but with the extreme 

 tips slightly dilated.

Colour.—" Whole body bright red."— D. The pectorals, of which no note was taken in the recent 

 state, appear, in the dried skin, externally, of a dusky colour, approaching to black, with 

 white rays ; the lower margin, however, is paler, and was probably originally red like the body : 

 inside, the colour is much the same, but variegated with a few white spots ; there are also 

 portions of a paler tint, probably the remains of a fine blue. 1 see no distinct trace of the 

 large deep black spot, said by Cuvier to occupy the seventh and eighth rays on the posterior 

 face of the fin. 



Taken in the Bay of Islands, New Zealand. The only respect in which it 

 differs from the description of the T. Jcumu by Cuvier and Valenciennes, is its 

 having one more spine in the first dorsal.

F 0RM . — Well characterized by the form of the snout, which is very obtuse, and as it were truncated, 

 with scarcely any notch in the middle ; the margins of the lobes are crenated with minute den- 

 ticles, immediately beyond which is a small sharp spine directed backwards ; further on, almost 

 immediately above the corners of the mouth, is a second similar, but somewhat larger spine. 

 There are also some minute spines on the temples, as well as on the ridge of the preopercle, 

 besides the ordinary spines, common to other species, which in this are all well developed and 

 vejy sharp. Dorsal spines smooth, or only the first with a faintly marked line of granulations ; 

 third longest. Pectorals long, contained exactly two and a half times in the entire length ; 

 when laid back, they reach to within two rays of the extremity of the second dorsal. Free 

 rays rather slender and tapering, with the extreme tips pointed ; not above half the length of 

 the pectorals. Ventrals rather longer than the free rays.
