three distal joints. Uropoda (fig. 11) not extending beyond the 
telson, basal plate somewhat triangular, posterior margin almost 
straight; exopodite small, situated on the inner lower border of 
the basal plate, endopodite nearly twice as long, setaceous and 
terminating in two long setae, situated at the top of the inner 
margin of the basal plate. Telson (fig. 12) slightly longer than 
broad, concave laterally, posterior margin straight, anteriorly 
with slight median depression. Lenghth rr mm. Colour (in 
alcohol) horny-brown with greyish rugosities.

Type—In the collection of the Indian Museum. 
The rugosities on the mesosomatic segments are more dis- 
tinct in some specimens than in others. The form of the 
uropoda, antennae and telson serve to separate it from its allies, 
and minor differences are also present in the mouth parts and 
thoracic appendages. 
Cubaris nacrum, n. sp. 
(Plate xi, figs. I-10.) 
Body oblong oval, strongly convex, smooth and shiny. Cepha- 
lon (figs. I and 2) small, with sloping anterior half, lateral lobes 
very small, median lobe absent, epistome almost flat. Eyes smail, 
situated antero-dorsally. Antennulae (fig. 3) small, 3-jointed, with 
numerous short, thick setae on the terminal joint. Antennae 
(fig. 4) short, covered with fine setae, flagellum 2-jointed, distal 
joint almost twice as long as the proximal one. First maxillae 
(fig. 5), outer lobe terminates distally in four incurved spines and 
five smaller almost straight ones, short, simple, hair-like setae on 
the outer margin; inner lobe terminally rounded, thin, and with 
two setose spines, broader at the base. Second maxillae (fig 6) 
thin and plate-like, terminating distally in a bi-lobed manner, the 
inner lobe having a rew of strong setae on theinner face. The 
segments of the mesosome are strongly convex, with the lateral 
plates not expanded excepting in the 1st mesosomatic segment. 
Segments t and 2 notched on their lower inner margins for recep- 
tion of succeeding segments. Lateral plates of metasomatic seg- 
ments 3-5 greatly elongated. Maxillipedes (fig. 7), the outer palp 
terminates in a multispinous process on the outer side and two 
small spines inwardly, the inner palp possesses a single terminal 
spine and two smaller ones on the outer border. Thoracic 
appendages (fig. 8) comparatively short, setaceous, the three distal 
joints being fringed on the inner side with numerous stout spines. 
Uropoda (fig. 10) not extending beyond the telson, basal plate 
triangular in shape, posterior margin pointed, outer half raised 
above the flat, inner half; exopodite very small, situated towards 
the base of the raised outer half, endopodite large and situated at 
top of the inner margin of the basal plate, but not extending 
beyond it. Telson (fig. 9) slightly longer than broad, contracted
