EEPOET ON THE STOMATOPODA. 
medians and two pairs of lateral ones, all six ending in spines, while none of the other 
carime end in spines. The telson has a broad convex median dorsal ridge wdiicli ends 
behind in a short acute spine, and on each lateral portion there are six obsolete 
symmetrical curved lines. The posterior border of the telson carries six lobes or teeth, the 
laterals and postero-laterals acute and straight, while the acute points of the submedians 
are curved inwards. There is a single rounded lobe between the lateral and the postero- 
lateral, six between the postero-lateral and postero-median, and none between the postero- 
medians, the space being filled up by the flattened bases of the spines which meet on the 
middle line. The sixth abdominal appendage is very large, and the terminal paddle of 
the exopodite is oval and ecjual in length to the proximal joint. The endopodite is long, 
curved, and narrow, and the prolongation from the lower surface of the basal joint ends 
in a short curved acute outer spine, and a much longer inner spine, which has a rounded 
tooth on its outer border and on its inner border six or seven acute teeth which increase 
in size distally. There is no dorsal spine on the basal joint. 
The ocular segment is wholly anterior to the long rostrum, and the eyes are directed 
forwards side by side, and are twice as long as wide and swollen in the middle, although 
the retinal portion, which is divided by a depression into halves, is a little wider than 
the base. The first antennae are short of the total length) and their somite ends 
dorsally in a pah- of lateral spines which point forward. The flagellum of the second 
antenna, including the three-jointed shaft, is nearly (f-f) as long as the first, and the 
scale is as long as the animal. 
The width of the carapace between the antero-lateral spines is about half (j-§) its 
greatest width, and almost exactly half its length. The dactylus of the raptorial claw of 
the second maxilliped is armed wdth six curved acute teeth, gradually increasing in size 
distally. The second joint has three movable spines on its inner edge, and the pectinations 
of its outer edge are arranged in an undulating line, with a convexity under each tooth of 
the dactylus (see fig. 2 PI. IIP). The appendages of the three pairs of exposed 
thoracic legs are flat, strap-shaped, and dilated at the tips. The lateral edges of the 
second thoracic somite are acute and a little curved forward, and those of the third and 
fourth somites are obliquely truncated, with subacute anterior and posterior angles. The 
fifth has no angular process. Sexes alike. 
Habitat. — Station 190, in the Arafura Sea, south of New Guinea, September 12, 
1874; lat. 8° 56' S., long. 136° 5 ' E. ; 49 fathoms; two males and one female taken 
in the trawl. 
Remarks. — This and the following species, Squilla fasciata, closely resemble the 
genus Chloridella in the shape of the eyes, and in the flattened strap-like form of the 
appendages to the exposed thoracic limbs. They agree in many points, as will be shown 
in the description of the second species, but there are so many well-marked differences 
that there can be no doubt of their distinctness.
