Paranephrops, subg. nov. The eyes large, as in Nephrops : the sides of 
the second thoracic segment, in the middle in front, with a spine, as in 
PotamohiuSf* and a shorter one beneath it : the lamellar appendage of the 
outer antennae extends considerably beyond the thickened basal joints 
of these antennae, and on the inside is nearly straight, and margined 
with longish hairs: the first two joints of the outer “foot-jaws” are 
spined within : the sides of the abdominal segments are not nearly so 
acutely angulated as in Nephrops : the middle plate of the tail is of one 
piece, as in Nephrops, and has the spine removed further back from the 
much rounded extremity : the first pair of legs is rather more slender 
than in Nephrops ; the claws inside are nearly straight, and furnished with 
moderately sized teeth ; the hands are but slightly grooved, and have a few 
rows of spines, largest on the inside : the second pair of legs is the short- 
est of the four hind pair, (while in Nephrops the fifth are so), the second 
are the longest, the fourth and fifth being nearly equal in length. 
This species, from the River Thames in New Zealand, connects the two 
genera Potamohius and Nephrops, in having the habit of the former, and 
combining the characters of both. 
Paranephrops planifrons, n. sp. The carapace is almost cylindrical ; 
the beak reaches beyond the pedicel of the inner pair of antenna), is 
straight, broad, flattened, and somewhat hollowed out above ; the sides 
have three teeth ; at the base, to the side, are two teeth, one placed 
before the other ; at the base of the beak, in the middle, there is a slight 
longitudinal abbreviated ridge ; the sides of the carapace, outside the outer 
jaw-feet, have many short bent spines : the abdominal segments are smooth 
above : the caudal appendages are finely striated at the end, and tinged 
with pinkish red : the thorax covered with minute hairs : the abdomen is 
of a yellowish, somewhat mottled colour ; each segment behind with a very 
narrow edge of pink. Length of largest specimen, 3 inches 8 lines, from 
the end of the tail to the end of the beak : length of smallest, 2 inches 
8 lines.
