Family ENTOMOLEPID &, fam. nov. 
Genus ENTOMOLEPISs !, gen. nov. 
Dorsal surface covered by a thin, oval, scale-like shield, beyond which the extremities 
of the limbs project only slightly. Antennules slender, simple; antenne prehensile ; 
swimming-feet two pairs (?). Abdomen short, slender, and, like the cephalothorax, 
completely covered by the scale-like dorsal investment. 
1. ENTOMOLEPIS OVALIS, sp. nov. (Plate XIII. figs. 18-21.) 
Outline, as seen from above, oval, widest in the middle, width equal to more than 
half the length (fig. 18). Antennules ten-jointed, slender, the penultimate joint 
bearing a long and stout sensory filament (fig. 19); the comparative lengths of the 
ae = 2 ars ocrecs OW a Oe oison a LO) Be 
joints as in the following formula: 55-77-35 7 7 19 3: Antenne three-jointed 
(fig. 20), the basal joint bearing at its apex a minute secondary branch ; second joint 
with a row of fine cilia on its distal half; third joint small and having a stout terminal 
unguis. Maxilla simple, two-jointed, the second joint pubescent and bearing three 
long terminal sete. Two pairs of foot-jaws (figs. 18 d, e), stout, prehensile, like those 
of Dyspontius. Siphon slender and of moderate length; swimming-feet two pairs (2) 
two-branched, each branch composed of three joints (fig. 18 f'). Length 1°3 millim. 
One specimen only was found among mud from a depth of 1-5 fathoms in Lyttelton 
Harbour. 
The foregoing description is incomplete, owing to some of the parts having been 
imperfectly seen, and it is to be hoped that some future observer may be enabled by 
the help of further specimens to describe more fully what seems to be a very remarkable 
form.
