 MODJOLA ARB011ESCEN8, Chemnitz, sp. 



Mi/tilus arhoresceiis, Chemnitz, Conch. Cab., xi., 1795, p. 251, 

 pi. 198, f. 2010-17; /(/., Reeve, Conch. Icon., x., lH57,ModioIa,

This workl-wide species occurred off Barranjoey in 55-84 

 fathoms, off Cape Three Points in 41-50 fathoms, and off Port

MODIOLA ALBICOSTA, Lamarck. 



Modiola albicosta, Lamarck, Anim. s. vert., vi., 1819, pt. 1, 

 p. Ill ; Id., Delessert, Recueil de Coq., 1841, pi. 13, f. 8a-6. 



Station 54. 



Accepting the usual interpretation of the species, this Tas- 

 manian shell is, by Delessert's figure, associated with Lamarck's 

 name Yet it appears to me as probable that Lamarck applied 

 the name M. alhicosta to the tropical M. 2)hil,ippina7'um, Hanley, 

 while he regarded* the Tasmanian shell as a variety of M. tulipa. 



The following record appears to be the northernmost locality 

 for this species : Jervis Bay, 10-11 fathoms. 



MODIOLA AUSTRALIS, Gra^/. 



Modiola australix, Gray, King's Survey Intertrop. Coasts Austr.,

 1857, pi. v., f. 21. 



Station 55. 



Gray's brief account is as applicable to M. albicosta. Reeve's 

 figure fixes the identity of the species. 



Dredged off the Crookhaven River in 11-15 fathoms.
