Coast of Koh Chick ('/s). Sound of Koh Chang, 3—5 fathoms, soft clay, very 

 common, taken in great numbers. Coast of Lem Ngob ('/2). Between Koh Kul and 

 Koh Kahdat, 10 fathoms, shells (-2). 



Bangkok (Siam) Coll. Dautzenberg (P. Fischer loc. cit.). 



Long. 2 — 27 mm. 



Distribution: — Salanga, on the west coast of Malacca (v. Martens). Mergui 

 Archip. (Philippi). 



It seems to me that there is a very close conformity and even transition, 

 between the forms representing the series: — oblonga, Phil. — oblonga, Dunker* — 

 nodifera, Martens^ — paucigranosa, Dunker.' I feel practically certain that all 

 these forms should be referred to one species. Anomalocardia pulchella. Dunker,' 

 is, no doubt, simply the present species. Philippi's statement' tiiat "Die Area ist 

 ganz vom schwarzen Ligament eingenommen" has, in Kobelt's diagnosis (Martini 

 u. Chemnitz, loc. cit.), been altered to "das schwarze glatte rautenförmige Band 

 lässt vornen und hinten ziemlich viel Raum frei;" this agrees also with the specimens 

 from the Gulf of Siam. Ed. Lamy'' considers A. oblonga, Phil., to be a form of 

 A. granosa L.

 Abth., p. 46, pi. 13, figs. 3 — 4. Recorded from Bangkok and Java by E. v. Martens who ("Zool. Ergebnisse 

 ein. Reise in Niederländ. Ost-Indien hrsg. v. M.Weber," 1897, p. 228) states that it is sold as food in 

 Bangkok, and that it lives in brackish water in these localities. It is a misprint when v. Mautkns (loc. 

 cit.) states, that A. nodifera is "17 mal so lang als hoch.'" 



' Novitates conchologicæ, p. 85, pi. 29, figs. 10—12. Martini u. Chemnitz, Conchyl. Cabin., VIII, 2 

 Abth., p. 100, pi. 27, figs. 1 — 2. Kobelt is also of opinion (in the last-mentioned work) that A. pauci- 

 granosa. Dunker is only a more feebly sculptured example of A. nodifera. Dunkek records it from 

 "Siam." 



* Novitates conchologicæ, p. 113, pi. 38, figs. 6—9. Dunker records it from "Japan." R. Stearns 

 from the east coast of Nippon. As Reeve had already in 1844 employed the same specific name for 

 an Area (Acar) from the Mediterranean, Dunker's name must certainly be altered. (For the reasons 

 which justify the adoption of Reeve's name A. pulchella, for the Mediterranean species instead of A. 

 imbricata, Poli, see "Bucquoy, Dautzenberg et Dollfuss, Les Mollusques mar. du Roussillon," II. p. 190).
