gissey and at Penzance, and on muddy sand on the east side of 

 Mount's Bay. At Scilly it has been obtained in berry in Crow 

 Sound in April. Under the name Pagurus fasciatus, Bell de- 

 scribed a " blue-banded Hermit-Crab " from a coloured drawing 

 made by Cocks of a specimen obtained in trawl-refuse in 1845, 

 but the species has not been found by any subsequent carcinolo- 

 gist. The typical fossorial Crustacea, Axius stirynchus, Leach, 

 and Callianassa subterranea (Mont.) rarely emerge from the sand 

 in which they burrow, so that they are very seldom obtained 

 entire. Fragments, however, especially of the latter, are not in- 

 frequently obtained in the stomachs of the Cod, Haddock, in 

 various Gurnards (Trigla hirundo, T. lyra, T. cuculus), occa- 

 sionally in Bays (R. clavata, R. metadata), and of Axius, rarely 

 in the Painted Bay {R. microcellata) ; and fragments of Axius 

 have been identified in trawl-refuse at Mevagissey. Two speci- 

 mens of Callianassa have been taken near the mouth of Helford 

 Biver by paying out a big length of rope so as to allow the dredge 

 to dig deep. In all probability neither species is scarce, but the 

 subarenaceous mode of life makes the chances of capture very 

 remote. Fragments, subsequently identified as belonging to 

 Calocaris macandrece, Bell, were obtained from the stomach of a 

 Sting Bay (Trygon pastinaca) of large size, captured in 23 fathoms 

 in Falmouth Bay. Upogebia stellata (Mont.), here taken as 

 synonymous with U. deltaura, Leach, is also fossorial, but appa- 

 rently does not burrow so deeply as those discussed above. 

 Occasional examples have been obtained between tide-marks 

 under Mount Edgcumbe, in dredgings on Queen's Ground, and a 

 single specimen five miles W. J S. of Bame Head (M. B. A.). It 

 occurs in Gerrans Bay down to 12 fathoms, and occasional 

 specimens have been obtained round Falmouth Bay about low 

 spring tide. At Scilly two have been dredged in fine sand in 

 40 fathoms east of Great Ganilly. A female in berry was taken 

 near Portscatho on July 23rd, 1908. Minuda rugosa (Fabr.) 

 occurs frequently in trawl-refuse from outside Falmouth Bay 

 in 30 to 45 fathoms, from near the Bunnelstone, from outside 

 the Wolf, and from 50 fathoms west of the Bishop. Young 

 specimens were taken by Cocks under stones at low spring 

 tide, and it was described by Bate as rare on stony ground 

 in 20 to 30 fathoms off the Dodman. At Padstow it
