Muller and Henle describe the colours of the dried fish as uniform. In Mr. Reeves's draw- 

 ing the ground colour is clove-brown, shaded obscurely with liver-brown, and with a reddish- 

 brown tint before the eye. There are also many paler wood-brown spots, which are sprinkled 

 with dark dots. Exterior to the eyes on each side, six of the smaller pale spots are arranged 

 so as to form a ring round a central one : similarly arranged spots occur near the margin of the 

 widest part of the disc on each side, and also more posteriorly, while nearer the mesial line on 

 each side there is an uninterrupted pale ring with a central spot, and a like ring exists on the 

 posterior lobe of the disc. The edges of the under surface, which are partially shown in the 

 drawing, are purplish-red. The spines correspond better with the letter-press description than 

 with the figure given in the ' Plagiostomen ' of Muller and Henle. Length of figure 1 4 inches, 

 width 8£.

This ray has much resemblance in form to the Tr. ivalga, as figured by Muller and Henle, 

 and still more to the Tenlcee shindraki of Russell (pi. 5), or to Tr. bennettii, M. und II. ; but it 

 has a considerably longer tail than either, and slight indications of both an upper and an under 

 short hem- like seam on the tail. The form of the disc is obovate,with a sharp point to the snout, 

 but no incurvature of the fore-edge, nor any decided convexity. Its breadth at the hinder 

 edge of the spout-holes is equal to its length, excluding the ventrals, and the tail measures 

 fully twice as much. The eyes are distant from the point of the snout one-quarter of the 

 length of the disc, and less than that from each other. Two small spines (or perhaps pores) 

 are situated side by side between the posterior edges of the spout- holes on the middle line. 

 Colour, pale flesh-red, almost white in parts; the tail darker towards the point. It is pos- 

 sible that this may be merely a variety of Tr. bennettii. Mr. Reeves thinks that it is the 

 voung of some species. Length or breadth of disc, 2\ inches.
