possible, too, that the small adipose fin may have got rubbed off in the ‘ Investiga- 
tor ’ specimens.” (MacArdle.) 
Since the above description was drawn up by the late Captain A. F. MacArdle 
other specimens have been obtained. There is no doubt that the adipose fin is want- 
ing in the species. 
The illustration of this species was published simultaneously with the report on 
the deep-sea fish of the “ Valdivia ” Expedition, among which is the new genus Tripld- 
phos^ Brauer. The resemblance between Triplophos elongatum, Brauer, and Photich- 
thys hemingi, MacArdle, is manifest, consequently I have changed the name of the 
latter to Triplophos hemingi. The presence of two teeth on the palatines of this 
species is a distinction from T. elongatum. 
Four specimens from the Bay of Bengal. Stations 165, 235, 277, 327. All have 
two teeth of moderate size set close together on each palatine. 
One specimen (No. -f-) has a tooth on the left side of the vomer. Règistered

One specimen from the Gulf of Manaar, 888 fathoms. Station 307, agrees very 
closely with this species. In the original description the tail was said to be three- 
fifths of the total. In this specimen vent is eleven inches from the nose and
