The published figures are not good, nor correct. Jeffreys' is not 

 square and open enough, the pillar is too large, the extremity of the 

 QUter lip is not sufficiently pointed, and it does not exhibit the con- 

 spicuous inner lip folded back on the pillar, as in Sowerby's; the 

 latter is quite difference from Jeffreys', and still further removed from 

 the type; the spire, though pointed as in this figure, should be bent 

 downward and not show above the crown. 



Although P. angidata and various other species are recorded in 

 these papers as derived from Sutherlandshire haddocks, it only means 

 that the haddocks were caught in Sutherlandshire waters, but it will 

 be obvious that the actual habitat of the molluscs is problematical. 

 Mr. William Baillie of Brora, who died in 1906 in his 77th year, 

 was an adept at the work of examining the offal of haddocks, and he 

 found it a most fertile field. He was a superannuated schoolmaster, 

 familiarly known in Sutherlandshire as "Teacher Baillie,'' and a good 

 local naturalist somewhat after the manner of the well-known Thomas 

 Edwards of Banff. It was his habit to go to the haddock-curers' 

 sheds and bring away buckets full of fish offal. The examination of 

 this was really a nauseous class of work, which would disgust most 

 inquirers, but his repulsion was overpowered by his zeal for natural 

 history, and he felt himself amply rewarded by the results. 



P. quadrata S. Wood. — Doggerbank, Scarborough, Filey, and 

 Whitby, occasionally cast ashore on the latter coasts; North Rona 

 45f., British Channel slope 69of. (Porcupine) ! Forbes and Hanley 

 give the best figures; the others are not sufficiently square, as if the 

 artist had drawn the shell from his right-hand side instead of directly 

 in front of him. A description of the animal has been left by Gwyn 

 Jeffreys among his notes.-' 



P. punctata Clark. — Low-water mark in places to 60 fathoms. 

 St. Martin's Flats, Scilly, under stones at low water and dead in 

 3o-4of. (Burkill and J. T. M.); Mayo and Sligo (Miss Warren) ! 

 Sutherlandshire (Baillie and J. T. M.) ; Tenby, Aberdovey, Portrush, 

 Lamlash 1 2-1 8f., off Loch Ryan 27f., lona i8f., Staffa 25f., Benbecula 

 Sound lof., Minch off Barra 53f., W. Orkneys 45f. 



var. cingulata Marsh., y^z/r//. of Conch., 1893, vol. vii., p. 265. — 

 Guernsey, Scilly, Land's End, Borough Island, Caldy Island, Tenby, 

 Killala Bay, Portrush, Sutherlandshire, Benbecula Sound, Minch off 

 Barra, and West Orkneys. Not the P. cingidata of Sars. 



Like P. catena, this appears to have its home along the Cornish 

 and South Devon coasts, but is sparingly though widely diffused 

 elsewhere. The shell varies in the degree of attenuation of the 

 crown, and occasionally the apical nipple appears above it. It differs
