488 ON THE FAUNA AND BOTTOM-DEPOSITS NEAR THE 30-FM. LINE 



Distribution. Geographical. South and West Norway, Sweden, Kattegat, Iiish Sea, 

 English Channel, Bay of Biscay, Mediterranean (Norman, No. 93 ; Meinert, No. 75 ; 

 Walker, No. 112; Bonnier, No. 10). 



Depth. Shallow water to 200 fathoms (Walker, No. 112, p. 80). 



Bottom-deposit. On nullipore ground in Irish Sea (A. 0. Walker), on shell sand, 30-50 

 fathoms, off Concarneau (Bonnier). Meinert records it in tlie Kattegat on clean sand, on 

 clean gravel, and on pure mud, as well as on the mixed deposits, sand, mud, and gravel, 

 or giavel, mud, and small stones. 



Anapagiirus laevis (Table VI.). This species was sometimes taken in 

 considerable numbers. It was more frequent on the fine sand than 

 Evjjcigurus cuanensis, but it was also taken on Grounds XL and IX., 

 where the deposit is a mixture of gravel and sand. It was most numer- 

 ous in hauls 104 (Ground II.), 93 (Ground IX.), and 90 (Ground V.). 

 Its absence from Ground XIII. (gravel and mud) is noteworthy, as this 

 ground in many ways resembles IX., where the species was numerous. 

 On the Bolt Head Shell Gravel it was present in 27 only, a haul which 

 in other respects gives indic'ations of being partly a fine sand ground. 

 On the Prawle Stony Ground it was taken in several hauls. On Ground 

 IX. Anrqr/f/urus was common in shells of TarriteUa communis, and was 

 also inhabiting shells of Nutica nitida, Mangelia gracilis, and Nassa 

 incrassata. 



Distribution. Geographical. Mediterranean, Azores, Bay of Biscay, English Channel, 

 Irish Sea, South-West Ireland, North Sea, Shetlands, Norway, Kattegat (Marion, Milne- 

 Edwards and Bouvier, Bonnier, Walker, Haddon, Metzger, Norman, Meinert). It is not 

 recorded fi'om the southern part of the North Sea. 



Depth. 5 fathoms (Metzger, No. 78) to 383 fathoms (Marion, No. 74). 



Bottom-deposit. Marion records Anapagurus laevis on deep mud in the Mediterranean 

 (273 to 383 fathoms) ; Pruvot (No. 98) on coastal sand and on deep coral and nuid (Medi- 

 terranean) ; Milne-Edwards and Bouvier (No. 80) on fine sand and on muddy sand in the 

 Bay of Biscay (74-98 fathoms), on gravel, sand, and broken shell at the Azores (71 

 fathoms) ; Metzger (No. 78) on stones (5-20 fathoms), on gravel and shell (12 fathoms), on 

 sand, on sandy mud, and on grey mud (50-80 fathoms) in the northern part of tlie North 

 Sea. Norman says it is common on the Haddock (soft) grounds in the Shetlands. Haddon 

 (No. 34) records it on coarse sand at the mouth of Bantry Bay (35-40 fathoms), and 

 Meinert (No. 75) on mud with sand or gravel (70-22 fathoms) in the Kattegat. 



It seems evident from the above records, and my own observations 

 tend to confirm this, that Ancqjagurus laevis occurs most frequently on 

 sand or mud grounds. 



Forcellana longicornis (Table VI.). Like Galothea dispersa this species 

 is found on all the grounds, and was taken in practically every haul, 

 often in large numbers. 



Distribution. Geographical. Norway, Sweden, Denmark, British Seas, Mediterranean 

 (Norman, No. 93). Courret (No. 31) states that it extends to tlie Canary Isles. 



Depth. From low-water (Bell, No. 9) to 100 fathoms (Bonnier, No. 10). Milne-Edwards 

 and liouvier (No. 80) do not record it from any haul in the Bay of Biscay deeper than 10 

 fathoms. 



Bottom-deposit. Tlie species is recorded from all kinds of bottom, though, as in the case 

 of many other very common and widely di.stributed species, very few records are to 

 be found.
