divaricating simple sete, which have hamate tips; outer 
margin of palm (fig. 7) furnished with regularly arranged 
long sete, inner margin (fig. 8) with stiff bent seta, each of 
which is furnished at the bend with two or three lateral 
prongs; alternating with these stiff sete are a series of short, 
blunt-topped spinules, and another series is seen behind these 
of asimilar character. Two anterior pair of perwopods with 
the dactylus scarcely more than one fourth length of pre- 
ceding joint. Last pereeopods (fig. 9) with meros and carpus 
subequal, propodos slightly longer, of good breadth (but not 
flattened out, as in L. fisstcornis), with four pairs of spines on 
the anterior and two or three sete on posterior margin; finger 
short, not exceeding one fourth of length of propodos, gradu- 
ally attenuated, two spines on the propodos at its base. 
Telson longer than peduncle of last uropods, and these have 
the branches very broad and foliaceous. As in L. pallida the 
first, second, fourth, and fifth segments of pleon have a central 
dorsal tooth. The colouring of the two specimens is alike 
and remarkable, the ground-colour pale with markings as 
follows of deep purple (at least that is their colour now in 
specimens which were mounted fresh from the sea twenty- 
three years ago) :—Antennez and antennules each with a spot 
on the last joint of peduncle; the purple colour commences 
on the head, across which it passes obliquely from behind 
forwards to the mandibles; thence the colour is suffused over 
all parts except the distal joints of the anterior pereopods 
until the middle of the last segment of perzeon ; here it passes 
obliquely forwards, and is continued through the thighs of 
the fourth perzeopods, leaving the thighs of the last pereeopods 
white, except that distally on them is a small spot of the same 
colour, which also appears in a spot near the base of every 
joint (except ischium and propodos) of three posterior pero- 
pods, as well as in blotches on the back of second and two 
following segments of pleon, and stainings at the base of the 
pleopods attached to these segments, on the distal portion of 
first and second and on the basal portion of the last uropods. 
Length 6 millim., exclusive of antenne. 
The absence of a produced calx to the wrist of the two 
gnathopods will, apart from all other characters, at once serve 
to distinguish this species from L. pallida, L. Kinahani, and 
L. fissicornis (M. Sars). In this respect it resembles L. equi- 
cornis, G. O. Sars; but from that species it may be known 
by the different antennules, the much smaller wrists of the 
gnathopods, longer and less flattened faite and shorter 
and stronger nail of last pereeopods, and by the four dorsal 
teeth on the pleon instead of one only.
