BULLETIN OF THE BUREAU OF FISHERIES. 
The funnel shows two large triangular groups of numerous organs symmetrically disposed. As in 
A . astrosticta four of these only are of the larger type, but in this species they do not lie in a single trans- 
verse line. The tip of the funnel is colorless and devoid of photophores. The number of these organs 
on the head and arms is no longer to be made out. 
Subocular organs are present, but the eyes are so damaged that their exact number and position 
can not be made out with certainty. They appear, however, to be relatively small and distant from 
one another. 
Color everywhere a brownish buff, heavily clouded with dark reddish chromatophores which are 
numerous even over the ventral surface. These combine with the bluish photophores to give a purplish 
cast to the entire animal.

Type. — Catalogue no. 214387, United States National Museum [S. S. B. 275]. 
Type locality. — Albatross station 4087, 306 to 308 fathoms, off Mokuhooniki Islet, northeast entrance 
to Pailolo Channel, fine gray sand bottom, July 21, 1902; one specimen. 
Distribution. — Hawaiian Islands (Albatross). 
Material examined. — The unique type is the only specimen known. 
Remarks. — Altliough in a rather badly macerated condition, as though taken from the stomach 
of some larger animal, the single specimen seen still retains enough of its original appearance to show 
features which forbid its reference to any of the previously described species of either Abralia or 
Ahraliopsis. The lack of terminal organs on the ventral arms and the pale red-dotted buccal membrane 
alone serve to establish its identity as an Abralia, while the large fins indicate that it will prove to 
belong to the typical section of that genus. The species to which A . trigonura most closely approxi- 
mates seems to be the A. andamanica Goodrich from the Bay of Bengal. The mantle of the Hawaiian 
species, however, appears to be relatively shorter and much more rapidly tapering, and such of the 
photogenic organs as can be made out fail to coincide in their arrangement with the description given 
by Goodrich, who fails to mention the definite series of these organs which here adorn the ventral 
aspect in so conspicuous a fashion that they can scarcely have been overlooked. 
From the other known Hawaiian species, A. astrosticta, it is widely different. The short conical 
body, larger fins, more numerous small luminous organs on the ventral surface, and much smaller sub- 
ocular organs are sufficient to distinguish it at a glance. As the specimens obtained of the two species 
are not very far from one another in size, it is evident that one can not be regarded as but a yoimger 
stage of the other.
