under Fucus at Portwrinkle, and among Laminaria at Looe. At 

 Polperro it is locally not uncommon on rocks down to 20 fathoms. 

 It is often found in trawl-refuse at Mevagissey, and is local in 

 Gerrans Bay. It is somewhat casual in its appearance in Fal- 

 mouth Bay and harbour, but in April, 1907, was abundant in 

 Carrick Koads, and is often present in trawl-refuse from the Bay. 

 A few years ago it was common near St. Michael's Mount among 

 Laminaria, but in 1903 it disappeared, and not a specimen has 

 been seen there since. It occurs in Gwavas Lake and at Newlyn, 

 but is not plentiful. It has been dredged in 25 fathoms east 

 of the Kunnelstone, and appears in trawl-refuse from the 

 Wolf. Specimens have been brought in at Porthgwarra and at 

 Sennen Cove. It is fairly common at St. Ives, has been obtained 

 in 15 fathoms north-west of Chapel Porth, at the Fistral Beach, 

 Newquay, and at Padstow. Females in berry are generally found 

 in April and May, and again from the middle of July till the 

 beginning of September. Couch's Smaller Spider Crab, M. 

 longirostris (Fab.), occurs in varying quantity all round the 

 coast from shallow water down to 45 fathoms, and is specially 

 common in places in fine sand and on " scuddy " gravel. It is 

 locally abundant in nearly all the trawling grounds from the 

 Eddystone to the Wolf. In the Bristol Channel it is not on the 

 whole so plentiful as on the south coast, but is of common 

 occurrence in dredgings and in trawl-refuse, and is frequent in 

 Crab-pots as far east as Widemouth Bay. At Millook, in July 

 and August, 1903, it was a serious pest among Lobster-pots. It 

 is occasionally taken at the Seven Stones, and appears to be 

 widely spread though not abundant between Land's End and 

 Scilly. It is common at Scilly on fine sand with the hydroid 

 Sertularella gayi in 40 fathoms to the east of Ganilly, and also 

 north of Menavawr. It is plentiful at the entrance to St. Mary's 

 Channel, and over a large area to the south-east of St. Mary's. 

 Large specimens have occurred in trawl-refuse from forty miles 

 west of the Longships. Females in berry usually appear along 

 the south coast in early spring and from the middle of July till 

 the third week in August. The Mediterranean species, M. 

 egyptia, A. Milne-Edw., was recorded as not uncommon on weedy 

 ground near Plymouth by Garstang, who recognized it " by its 

 stripes of reddish brown pigment." Identification, however, by
