28. Ponteciella abyssicola, Th. Scott. 
Artotrogus abyssicolus, Th. Scott, Trans. Linn. Soc., 2nd ser. Zool. 
vol. vi. p. 128, tt. xii., xiv. 
Distr, 2°N.-4° 8., 6°-10° E. (?235-360 fathoms) ; Naples; 
99° W., 3° S. (2 1800 m.); 124° W., 9° N. (1000 m.) (Hape- 
dition of the ‘Vettor Pisani’). 
* Whether Dyspontius striatus, marginatus, and conspicuus, Hesse 
(Ann. Sc. Nat. 5 sér. vol. vi. p. 69, t. iv.), really belong to this or to 
some other genus, is not possible to decide. 
+ The specimens regarded by Scott as males can scarcely be such ; 
neither are they mature males, as the anterior antenne are not clasping- 
organs, nor immature, as the abdomen is said to be 6-jointed.
