6. Submedian carinae are present on the last three thoracic and on all the abdo- 



minal somites l , and on the sides of each between the lateral and intermediate 

 carinae there is a flattened triangulate prominence. 



7. The telson bears a great resemblance to that of S. fasciata, but there are two 



or three long continuous carinae on either side of the median crest in place of 

 the one found in that species. According to Hess' figure the first and third 

 of these carinae are connected proximally, while the second and third fuse 

 posteriorly and are continued as a single keel to the apex of the submedian 

 tooth. On the surface of the telson outside these carinae there is an oblique 

 row of short ridges or tubercles. The submedian teeth have movable tips and 

 are placed close together, the margin occupied by the intermediate denticles 

 being thus much longer than in S. fasciata. There are three or four minute 

 submedian denticles, nine or ten intermediate and one lateral. The praelateral 

 denticle appears to be absent. 



The type of Squilla miles, which measures 172 mm., was found at Sydney (Hess) 

 and the only other known example, a male about 90 mm. in length, is recorded from 

 Victoria (Miers).

This species is allied to 5. fasciata, but is easily distinguished by the absence of 

 carinae on either side of the median crest of the telson. 



The whole dorsal surface is smooth and polished. On the carapace the .median 

 carina is wholly absent, though the small mid-dorsal pit is visible ; fine intermediate 

 carinae are found on either side of the gastric groove, but the laterals and marginals 

 only exist in the extreme posterior part of the carapace behind the cervical groove. 

 The lateral margin is very obtusely angled in front of the rounded postero-lateral 

 corners and the antero-lateral angles are produced to a sharp spine that does not reach 

 the level of the rostral base. The anterior margins on either side of the rostrum are 

 distinctly sinuous. 



The rostrum is about one and a half times as long as broad, its lateral margins 

 are sinuous — concave anteriorly — and converge to a narrow rounded apex. In its 

 anterior half it may bear a very feeble longitudinal ridge, but it is never definitely 

 carinate. 



The eyes are elongated. The cornea is distinctly wider than the stalk ; its breadth 

 is about two-thirds the total length of the whole organ ; the corneal and peduncular 

 axes are a trifle oblique. The antennular peduncle is shorter than the median length 

 of the carapace. The mandibular palp is present and is three-segmented. 



The dorsal carina of the raptorial carpus terminates abruptly before reaching 



1 It seems that Hess, when he mentioned three longitudinal carinae on the abdomen, did not reckon 

 the marginal.
