produced, with the lateral angles blunt and the inferior acute ; 

 second and third segments truncated laterally, with the 

 angles rounded. The carinse of the fifth and sixth postabdo- 

 minal segments terminating in spinules. Last postabdominal 

 segment with a strong median carina, which is interrupted 

 near its base and ends in a spine ; upper surface armed with 

 series of nearly confluent punctulations, which are obsolete 

 except toward the lateral margins ; there are eight or ten 

 acuminate spinules between the submedian marginal spines, 

 and between these and each of the first lateral spines. Inner 

 and longer of the terminal spines of the basal prolongation of 

 the uropoda bearing a small rounded lobe on its outer margin. 

 Length nearly 3 inches. 



Hob. Mediterranean (common) ; Channel (rare). 



There are in the British-Museum collection two male ex- 

 amples from Nice, and a smaller male from Sicily ; a male 

 from Brighton (Dr. Mantel!) , another from Cornwall (Mr. 

 Laugklan), also two males without definite locality presented 

 by J. B. Jukes, Esq.* 



It is remarkable that all the specimens in the Museum col- 

 lection are of the male sex. 



** Dactyli of the raptorial limbs armed with six spines. 



Squilla fasciata. 



Squitta fasciata, De Haan, Faun. Japon. Crust, p. 224, pi. li. fig. 4 

 (1849). 



This species is described by De Haan as having the cara- 

 pace very convex in the middle, with the sulci distinct and 

 produced to the posterior margin ; antero-lateral angles acutely 

 spinose. Rostral plate trigonous, narrower anteriorly. Lateral 

 process of the first exposed thoracic segment terminating in an 

 acute spine. Postabdominal segments gradually increasing 

 in width, the fifth scarcely twice as broad as the first. Ter- 

 minal segment sexcarinulate, the carinules alternately longer 

 and decurrent from the base, and shorter and decurrent to- 



* No locality is given in the register for these specimens ; but most of 

 the crustaceans collected by Jukes were from the Australian seas, and 

 that these Squillce were thought to come from the same locality is evi- 

 dent from the label attached to one of the specimens. If the Squilla 

 Desmarestii be indeed an inhabitant of these regions, it will be a fact 

 hitherto unparalleled in our knowledge of the distribution of the group, 

 and the more remarkable as there exists a species (S. fasciata) nearly 

 allied to the & Desmarestii in the Japanese region, and which, one would 

 suppose, would be also its representative in the Australian seas. 



These are the specimens referred to by Dr. Woodward (Ann. & Mao-. 

 Nat. Hist. 1879, ser. 5, vol. iv. p. 319) as being the nearest recent allies to 

 his S. Wdherelli from the London Clay.
