284 A HISTORY OF RECENT CRUSTACEA 
claws have seven teeth. This species, originally described 
from Chili, has been found also in New Zealand, a locality 
to which Squilla nepa, Latreille, has likewise been assigned, 
but of its occurrence there Mr. Charles Chilton thinks there 
is much doubt. The genus Chlorida, Eydoux and Souleyet, 
184], had a preoccupied name, which was changed into 
Chloridella by Miers in 1880, but Professor Brooks thinks 
it unnecessary to separate it from Syuilla. 
Squilla scabricauda, Lamarck, is from the Antilles. 
Desmarest’s figures of it (see Plate XIII.) are designed to 
show the series of limbs as distinctly as possible, the small 
first maxillipeds being pulled back behind the large second 
pair, which would otherwise obscure them. The species 
should probably be referred to Lysiosquilla, the genus next 
mentioned. 
Lysiosquilla, Latreille, 1825, has the terminal joint of 
the second maxillipeds not enlarged at the base, and armed 
with more than six spines. The pleon is depressed, loosely 
articulated, and wide. The outer spine of the ventral 
prolongation from the peduncle of the uropod is usually 
longer than the inner. Between the submedian and inter- 
mediate marginal spines of the telson there are no more 
than four secondary spines, and there is often only one 
spine. The species Coronis scolopendra, Latreille, has been 
incorporated in this genus, the generic name Coronis, 
though earlier, having been preoccupied. Lysivsquilla 
maculata (Fabricius) has nine spines on the claw of the 
adult male, and seven or eight on that of the female, those 
of the female moreover tending to weaker development, 
although, it is said, such ‘ secondary structural differences 
between the sexes are extremely rare among the Stoma- 
topoda.’  Lysivsquilla spinosa (Wood Mason) is found at 
various parts of New Zealand, and is there the only species 
of the genus, according to Mr. Chilton, who has recently 
re-described it, with special reference to the apparatus on 
the first pleopods of the male. Lysiosquilla excavatria, 
Brooks, has on its claw fourteen or fifteen short curved 
pointed teeth, besides the long terminal one. The whole 
dorsal surface, rostrum and telson included, is smooth and
