taken in Torbay. Between the rostrum and the spine on the 
front at the other side of the eyes they have the margin less 
boldly sinuous, and in the second trunk legs the widening of 
the third joint is less developed. The apex of the telson is 
in specimens from both localities furnished with six spines, 
the intermediate pair the longest and strongest, the central 
pair slender, much longer than the outermost. Of four dorsal 
pairs two are tolerably conspicuous, whereas de Haan says 
that in his N. japonica there are no dorsal spines on the telson. 
Length, 35 mm. 
Locality.—Off Cape St. Blaize. Depth, 40 fathoms. A 
small specimen about 16mm. long, with less inflated eyes, 
was taken between Bird Island and the mainland in Io to 
16 fathoms. It is probably not full grown. A specimen, 
an inch long, was taken in 30 to 32 fathoms, Knysna Heads, 
N.E. by N. 3 N., 2 miles.

In the first part of the ‘“‘ South African Crustacea ”? numerous 
references for this family prior to 1898 have been already sup- 
plied, with a discussion of its character and constituents. To 
the latter should be added the genus Prionocrangon, Wood- 
Mason, 1891, distinguished from the rest by the absence of eyes, 
agreeing with Sabinea and with Nobili’s new genus Corallio- 
crangon, in having the second pair of trunk-legs simple, and with 
Philocheras in having only five pairs of branchiae. In referring 
Crangon nanus, Kroyer, to the new generic name Philocheras, I 
overlooked the circumstance that Kréyer’s species had been 
identified with Crangon bispinosus, Westwood (see Norman, 
Ann. Nat. Hist., Ser. 6, Vol. VII., p. 269, 1894). As Westwood’s 
species was instituted in 1835, and Kréyer’s not before 1842,
