I825.J not taken Notice of by Lamarck. 13^ 



1. MOLLUSCA CONCHIFERA. 



AsPERGiLLUM Javanum, Lam. disco subperforato, tubuli 

 fimbriaj distinctis crassis, Martini, t. 1, f. 7. 



A. Listeri. disco confertissime perforato, tubulis fimbriaj con- 

 fertis tenuibus, List. t. 548, f. 3. A. vaginiferum, Lam. ? I 

 think that all the species of this genus will be found to have a 

 foliaceous mouth to their tube when they are perfect. 



Ml/a Bitighami. Sphsenia Binghami, Turtoii. 



Anatina. The shells of this genus always have a loose piece 

 in their hinge which is very much developed in A. Norvegica, 

 but is dictinctly to be found in A. Pratenuis and A. Myalis. 



Anatina globosa. Mya globosa, Wood, t. 24, f. 4—6. 



An. Nicobarica. Mya Nicobarica, Gmelin. 



An. pratenuis. Mya praetenuis, Montague, t. 1, f. 2. 



An. distorta. Myadistorta, Montague, t. 1, f. 1. 



An. convexa. Mya convexa, Wood, t. 18, f. 1. 



An. Norwegica. Mya Norwegica, Chemn. x. 1647, 1648. 

 Amphidesma'corbuloides, Lam. Hist. 492. 



An. membranacea. Mya membranacea, Dillwyn, 48. 



LuTRARiA vitrea. Mactra vitrea, Chemn. xi. f. 1959, 1960. 



L.fragilis. Mactra fragilis, Chemn. vi. f. 235. 



Mactra Campechensis. List. 304, f. 141. 



M. squamosa. Solen squamosus, Montague. 



Erycina. Lam. Several of Lamarck's Crassatella agree 

 with the character of this genus ; therefore I have removed them 

 as far as I have any grounds. The recent species of Lamarck is 

 a Cytherea. 



Ery. denticulata. Testa elongato-cuneata, dentibus lateralibus 

 serruiatis. 



Ery. striata. Crassatella striata, Lam. 483. 



Lry. subangulata. Crassatella cuneata, Lam. 483? 



Lry. glabrata. Crassatella glabrata. Lam. 482. 



Ery. ovata. Testa ovato-elongata, cardine in medio te sas 



Ery. Austratis. Mya Novaj Zealandise, Cliemn. vi.f. 19, 20. 



UngulIzNA. The only species of this genus that I have seen 

 appear to be too nearly allied to Ampliidesma to be kept dis- 

 tinct. 



Amphidesma decussatum. TeUina decussata. Wood, t. 43, 

 f. 2, 3. 



Amph. cordiforme. Tellina cordiformis, Chemn. xi. f. 19, 

 41, 42. 



Amph. variabil.e. Tellina obliqua. Wood, t. 41, f. 4, 5. 



Amph.f nitens. Mya nitens, Montague. 



CoiiBVLA labiata. Mya.\iihii\ta., Muton, Lin. Trans. 



Pan DORA glacialis. Testa semicircularis, cardine submedio, 

 margine dorsali recto.
