' The Editors do not acknowlt-dge the validity of many of 

 thi-se species, but merely illustrate them : as to the arrangement 

 it does not pretend to be scientific, but uspful for grouping the 

 allied forms of shells, not moUnsks. .Some species only just 

 publishi'd have been added in our last part to fill up vacancies 

 in the plates. 



- Journ. Asi. .Sou. Ben. 1873, pt. 2. pi. 17. 



' lu Prime's monograph of this genus we find recorded as 

 Indian five of his species, which are wholly unknown to us : C. 

 subradiata (An. Lye. N. York, 1864, vol. 8, p. 75, f. 2.3), C. 

 Agrensis (do. f. 24), C. parvula (do. p. 76. f. 25), C. eon.san- 

 guiuea (do. !867, vol. 8, p. 417). C. imperialis(do. 1869. vol. 0:. 

 The last is stated to come from Pondicherry, always a suspicious 

 locality; the two first are probalily immature, tlie two next in- 

 sufficiently defined. Chemnitz (Conch. Cab. vol. 6, f. 321) has 

 erroneously identified as the fluviatilis of JliiUer, a Tanjore 

 shell which may possibly be intended for occidens. The 

 Veloritfe being estuary shells (C. Cyjirinoides, Gray, and I,'. 

 Cochinensis, Han.) are purposely omitted. 



' Lea justly remarks that although edentulous when mature, 

 the ymng have manifest teeth. The name has been changed 



because D'Orbigny had previously published a Soleiiifcjrmis in ■ 

 Guerin's Maff. ile Zuol. 



' Monocondyla-a Ava;, Th. J. Asi. Soc. Beng. 1873, pt. 2, \k 

 209, pi. 17, f. 5. 



" It is possible that the U. luteus of Lea (J. Xc. Philad. 

 n. s. vol. 3, pi. 24, f. 4) from Newvillc, Tavoy, may be identical 

 with one of our list, but the specimen delineated was in too l.iad 

 a condition for positive recognition. 



^ The U. exanthematicns of Kuster s Chemnitz (Unio, p. 243, 

 pi. 81, f. 2) has somewlnit the aspect of this shell; it is said to 

 come from that indefinite locality the " E. Indies." 



' Morch states the U. gibljus of .Spengler (Skriv. Nat. 

 Kioben. vol. 3, pt. 1) said to come from Tranquebar, is allied to 

 this: its Latin description is utterly inadequate for the purpose 

 of identification. 



' To this may be referred the U. Jleroilabensis of \'on 

 dem Busch in Kuster's monograph of Unio (ed. Chemn. U. 

 pi. 78, f. 4). Perhaps, too, the U. Rajahensis of Lea (Obs. 

 I'n. vol. 3, p. 77, pi. 23, f. .53), which has been vainly sought 

 for in the Eajali's Tank near Calcutta, its recortled locality, may 

 prove, if indigenous, a distorted form of this or someallied species.
