TOMI.IN : DESCRH'TION OF ANTIMITRA (?) HEVVITTI N.SP. 157 



more prominent ones occurring very irregularly. All tiie ribs on the 

 last three whorls are more or less evidently and regularly spotted with 

 brown. This is particularly noticeable on the peripheral rib, which 

 is broader than the rest and traceable on the two whorls preceding 

 the body one. 



Length, 7 mm. ; diam. max., 275 mm. 



Habitat : Port Alfred, not uncommon, East London. 



Type : In my own collection. 



Named in honour of the able Director of the Albany Museum. 



The correct usage of the generic name Mitromorpha is pointed out 

 in Proceedings of the Malacological Society of London, vol. xii, p. 

 32S, and it is at present uncertain where these South African forms 

 should be placed. 



Giant Race of Cardium edule L. — While in Orkney in 1917, I came across 

 a giant race of cockles at Congesquoy, near Stromness. Except that they are 

 considerably larger in size, they correspond to Cardimn ediile var. major B.D.D. 

 (Mollusques Marins du Roussillon, ii, 292, and plate 46, fig. 6). The adults 

 mostly range from 53 to 66 mm. in breadth, and average about 60 mm. ; but I 

 obtained three monsters outside this size even ; my largest measures 76 x 64 mm., 

 and 51 mm. in thickness; k weighed 5 ounces living; the shell approximately 

 3 ounces, and containing about r ounce water and i ounce body. All the cockles 

 in these sands are of the same type, and the smaller specimens are perhaps even 

 more striking, shells up to 53 mm. showing signs of immaturity. One day we took 

 270 live cockles, weighing 28 lbs., and feasted royally on them. The animal does 

 not appear to differ from typical Cardium edule. All the features of the shell are 

 emphasized in proportion to its size and solidity, the ventral margin tends to be 

 straighter than in the type, and the ribs more numerous {27 to 30). Their habitat 

 is clean sand, and the water is clean and presumably somewhat fresh, as it is just 

 below the outfall of the Loch of Stenness. Associated with Cardium edule are 

 Venus gallina var. laminosa, Spisula subtruncata var. striata, Tellina tenuis, and 

 Alya arenaria, and lower down Eiisis siliqua — all well developed in size, but none 

 gigantic. — R. Winckworth {Read before the Society, December loth, 1919). 



Milax g-ag-ates in Gloucester West. — On September 5th, 1920, under some 

 pieces of cardboard lying on a pathway at Redland, Bristol, I found some half- 

 dozen of the above slug. I believe it has not been taken in. this vice-county before. 

 Mr. J. VV. Taylor, who kindly identified them for me, informs me they were not 

 fully grown, and still showed the pale keel said to be characteristic of the juvenile 

 stage. If retained to the adult, they would be referable to the var. benoiti. The 

 roadway is only about one hundred yards long, a high garden wall on one side, 

 and on the other an open field. On the stone-coping of the pathway, which is 

 grass-covered, I also took V. pulchella, V. costata. Vertigo pygmiza (in numbers), 

 and a couple of Punctum pygmccum. — D. BACCHUS. {Read before the Society, 

 Nov. 10th, 1920).
