REPORT ON THE STOMATOPODA. 35 



medians and two pairs of lateral ones, all six ending in spines, while none of tlie other 

 carinae end in spines. The telson has a broad convex median dorsal ridge which ends 

 behind in a short acute spine, and on each lateral portion there are six obsolete 

 symmetrical curved lines. The j)Osterior border of the telson carries six lobes or teeth, the 

 laterals and postero-latcrals acute and straight, while the acute points of the submedians 

 arc 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 equal 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 (^Vrj of t]ie total length) and their somite ends 

 dorsally in a pair of lateral spines which point forward. The flagellum of the second 

 antenna, including the three-jointed shaft, is nearly (f§) as long as the first, and the 

 scale is ^y^ as long as the animal. 



The width of the carapace between the antero-lateral spines is about half (ff ) its 

 greatest wadth, and almost exactly half its length. The dactylus of the raptorial claw of 

 the second maxilliped is armed with 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. III.). The appendages of the three pau-s 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 aud one female taken 

 in the trawl. 



Remarks. — This and the following species, Squilla fasciata, closely resemble the 

 genus CIdoruIeUa 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 wUl 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.
