G. M. Tuomson.—On New Zealand Crustacea. 931 
Colour pale-yellowish, covered with small black spots. Length about 
0°25 inch. 
Hab. One specimen of this interesting Crustacean was obtained among 
some seaweed washed up on the beach near the mouth of the Taieri river. 
It differs from the figure (given in Brit. Sess.-eyed Crust.) in having more 
slender limbs with the exception of the first pair; otherwise it agrees per- 
fectly. This species has hitherto only been recorded from the English and 
French coasts, and from the Mediterranean. 
Amputropa NorMALIA. 
Sub-fam. LysianassIDEs. 
Genus Anonyx, Kroyer. 
Superior antenne short, the peduncle very large at the base, and fur- 
nished with a secondary appendage. Mandibles with a smooth incisive 
margin, and no secondary plate, and having an appendage. First pair of 
gnathopoda subchelate; second pair long, slender, feeble, rudimentary, 
subchelate. Telson single, squamiform, entire or cleft. 
(The characters on which this genus is separated from Lystanassa are 
very insufficient, being mainly subchelate nature of the first pair of gnath- 
opoda, and secondly the cleft telson. The first species following is an 
Anonyx in all respects, except that its telson is entire, which is the case also 
with A. plautus, Kroyer, an European species.) 
1. A. corpulentus,n. sp. 
Pl. XVII., fig. 1. 
Cephalon rounded in front, hiding the antenne. Pereion greatly dis- 
tended, so as to give the animal a very corpulent appearance ; coxe very 
deep. Eyes not appreciable. Superior antenne short and very thick ; 
basal joint cylindrical, hardly longer than it is thick, two following very 
short; secondary appendage minute, 2-jointed ; flabellum slightly longer 
than peduncle, tapering, 4-jointed, first joint as long as or longer than the 
next three, setose below. Inferior antenne slender, subequal with the 
superior ; second and third joints of peduncle long, and subequal with the 
6-7-jointed flagellum. Gmnathopoda small; first pair densely fringed below 
with simple hairs; propodos narrowing to the extremity, lower margin 
Without a distinct palm; dactylos curved ; second pair very slender, with 
tufted sete on the lower margin, propodos about three times as long as 
broad, with a small curved dactylos. Four anterior pairs of pereiopoda 
subequal, slender, naked, with narrow basa; fifth pair short, setose, and 
with the basa dilated into wide, rounded, squamiform plates. Three poste- 
rior pairs of pleopoda terminating subequally, naked. Telson short, entire, 
rounded. ‘Length 0-23 inch. Colour yellowish. 
Hab. Dredged in Paterson Inlet, in 8 fathoms.
