STELFOX: GASSIBS COLLECTION OF PISIDIA. 65 



Card No. 130, " P. amnicum. Tellina, Miiller. 



Eau Bourde, St. Medart, Garonne, Isle Moron." ^ 

 Six shells in perfect condition. 

 Typical P. amnicum in various stages of growth. 

 Card No. 130b. " P. amnicum, var. B. sulcata, Gassies. 

 Esteys des Landes, de la Gironde." 

 One shell ; perfect. 



A half-grown shell of P. amnicum with no traces of sulcation : 

 in fact, a particularly smooth example. 

 Card No. 131. " Pis. intermedium, Ga^ssies. Exauctore. 

 Marcamps, Bassens, Creon." 

 Three specimens : perfect. 



Typical of the shell usually known as intermedium ; I have 

 opened the two largest, and have no hesitation in referring 

 this species of Gassies's to a large race of P. casertanum.. 

 The chief characters of the hinge of this form are the long, 

 rather narrow ligament pit ; the long sweeping laterals and 

 the proportionately small cardinal teeth. I have made 

 drawings of the left-hand shell (the largest of the three) on 

 the card, and propose to regard it as Gassies's type of 

 P. intermedium. 

 Card No. 132. " Pis. casertanum. Cardium. Poli. 

 Libourne, St. Emilion, Blaye, &c." 



10 perfect shells ; 3 perfect valves (1|- pair) ; and 2 partly 

 broken shells. The right valve at the right-hand side of the 

 bottom row (i.e. the last shell on the card) belongs to 

 P. nitidum, Jenyns. All the rest are referable to P. caser- 

 tanum ; but various forms are represented and it is evident 

 that the specimens are from various localities. On the back 

 of the card is scribbled in pencil : 



" Var. niaj. / fontinale. / Teste Jeffreys. / P. fontinalis 

 NUss. 1822. / P. casertanum Poli / 1791 ! 1 " 

 Card No. 132b. " P. casertanum var. B. = P. limosum, Gassies. 

 Libourne — St. Emilion — Blaye, &c." 

 6 shells in perfect condition. 

 Originally there would appear to have been three shells stuck on 

 the card — the first of these has disappeared — and under these is 

 written in ink a figure " 1 " where the first shell was and a figure 

 " 2 " under each of the others. On the back of the card is written 

 in ink (over pencil) " 1. Pusillum Jen. / fid. Jefir. 2. 2. fontinalis / 

 fid. Jefireyss [sic]. / is. casertanum / var. limosuni ? G." When (?) 

 the first shell was removed the note " 1 " on back appears to 

 have been struck out in ink. The two shells referred to as " 2 " 

 " 2 " are both P. j^^'^'sonatum, Malm,^ 1855. Both belong to a 



^ I have copied the exact title on eacli card.
