A single small specimen of a species of Chaunax, 37""" long, was ob- 

 tained September 4, at station 869, at a depth of 192 fathoms. 



While there is a general agreement between the specimen described 

 from Madeira by Lowe under the name Chaunax ])ictus* and the im- 

 mature individual of the same genus before me, there are certain charac- 

 ters, such as the slightly smaller number of tin-rays in dorsal and cau- 

 dal, and the ditference in the shajje of these tins in the latter, which 

 renders the question of their identity somewhat doubtfnl. I am unwill- 

 ing, however, to establish a new s[)ecitic name on this immature speci- 

 men, particularly since the shajie of the tins is likely to be modified 

 with age, and the difference in the radial formula is^ hardly of specitic 

 imijortance. The specimen is therefore provisionally referred to Lowe's 

 species. - A larger specimen from our coast is much to be wished for. 

 Lowe's was 400"^"' (16 inches) long, and " was taken with an ordinary 

 bait and line at the Picos, a rocky shoal about a league from the shore of 

 Camera de Lobos, a village live or six miles to the westward of Funchal, 

 on the lUth of Marcb, 1846"; depth of water not stated. The color of 

 this specimen was bright orange above, rosy at the sides, and with fins 

 and tips vermilion; on the belly rosy white, with fins vermilion. 



The color of our siiecimeu, No. 26021, is brownish gray. The rostral 

 tentacle is nearly as long as the diameter of the eye.
