Rostrum broadly and abruptly truncate at the extremity., its 

 sides bending upwards, so that it is deeply sulcata in the 

 centre. Carapace bearing a single central spine, on either 

 side of which and between it and the margin are three slight 

 lobe-like folds. Between this portion of the carapace and its 

 hinder margin is a deeply cut sulcus arching forwards at the 

 sides. Antennal scale short and very broad, unusually ex- 

 panded on the inner side at the base. Maxillipeds with the 

 two terminal joints broad and flattened. Second pergeopods 

 very short, just reaching the base of the hand of the first 

 pair, the chela well developed (for a Crangon). Animals more 

 or less speckled with dark brown, the carapace sometimes being 

 entirely suffused with that colour. The epimera of the second, 

 third, and fourth segments of the pleon are generally marked 

 with the same colour, and also two transverse bands, one on 

 the fourth segment, the other across the telson and uropods. 



Specimens of this species are in my collection from Jersey 

 [Sinel and Co.), Guernsey and Falmouth {A. M. N.), Star- 

 cross, Devon {Mr. C. Parker)^ Weymouth [Mr. P. II. Gosse). 

 I have also recorded it from Shetland, but cannot at this 

 moment lay my hands on the specimens to re-examine them. 



Other recorded localities are Salcombe Bay [Mr. Alder)^ 

 Dublin and Belfast [Dr. Kinahan)^ Galway [Dr. Melville)^ 

 Mediterranean (various authorities).
