siderable distance, and with a short spine at the anterolateral 

 angles. Kostrum oblong-oval, rounded at its distal end, and 

 with a short median longitudinal carina. Exposed thoracic 

 segments with six, and postabdominal segments with eight 

 longitudinal carinae ; the median carina is obsolete, or very 

 nearly so. The first exposed thoracic segment is laterally 

 prolonged into a short straight acute lobe ; the two following 

 are laterally obliquely truncated, the lateral margins being 

 entire and the postero-lateral angles acute ; the last thoracic 

 segment is not laterally produced, and is furnished with a 

 small subacute prominence at its antero-lateral angle. On 

 the first to fourth postabdominal segments all the carinas, 

 except the submedian ones, terminate in spinules ; on the 

 sixth segment, and usually on the fifth segment, all the carinas 

 end in spinules. The terminal segment is armed on its upper 

 surface with a strong longitudinal median crest, which termi- 

 nates in a spinule, and is covered with numerous shallow pits 

 symmetrically disposed in curved lines ; the spines of the 

 lateral margin are considerably thickened ; there are from six to 

 eight denticles between the submedian spines of the posterior 

 margin, and eight or nine rounded prominences terminating 

 in spinules between the submedian and each of the first lateral 

 marginal spines. The basal portion of the antennae is without 

 fleshy appendages ; the basal scale is elongate-ovate and sub- 

 acute ; the spines of the dactyli of the raptorial limbs are all 

 of them well developed ; the distal prolongation of the basal 

 portion of the uropoda terminates in two unequal spines, the 

 lobe on the outer margin of the inner of these being obsolete 

 or nearly so. Length rarely exceeds 7 inches. 



Hah. Mediterranean (very common) ; Channel (very rare). 



Specimens are in the British-Museum collection from Nice 

 (Old, Collection)] Adriatic Sea (G. Cuvier) ; Gibraltar (Mr. 

 Laugh-in) ; Gulf of Aorta (S. Saunders, Esq.) ; Mediter- 

 ranean, without precise locality (Admiral Spratt, Mr. Laugh- 

 rin) ) and others without locality, among them one from 

 Donovan's collection, labelled S. vulgaris, by Leach, and one 

 collected by Surgeon Rayner, of H.M.S. ' Herald,' probably 

 outside of European seas. 



Prof. Bell records the capture of a single female, by Mr. 

 Couch, on the south-west coast of England ; and B. Capello 

 includes it in his list of Crustacea of the coast of Portugal. 



Bianconi (no doubt erroneously) refers specimens obtained 

 at Mozambique to this species (Mem. Accad. Bologna, ix. 

 p. 210). 



It is probable that Herbst, under the name of S. digitalis, 

 included more than one species of Squilla. His figure, which
