As the shell of Rumpbius is marked with a number, it need not 

 be from Amboina. The description of Favanne has much in common 

 with Blainville's, chiefly in respect of the colours and septa ; it is 

 perhaps even from the same specimen. It is possible that this spe- 

 cies is identical with, the two preceding. 



The annular rings in Rumphius' figure, and the reddish colour 

 mentioned by Favanne and Blainville, remind one of T. michaudii, 

 var. from the Philippines.

T. libera, agglutinans, repens, alba vel pallide isabellina, hie illie 

 lineis interruptis et punctis ohsoletis rufis ; anfr. primi parvi,

 sigmoidei, aperturam versus rapide crescentes, liris obsoletis 

 longitudinalibus leviter spiraliter tortis, tuberculis acutiusculis 

 subremotis ornatis ; interstitia lirulis planis confertis incequa- 

 libus 5—Q ; stri(S et rugce incrementi parvce, flescce, in intersec- 

 tionibus minutissime granuloso-squamosis ; apertura circularis, 

 faucibus regulariter scrobiculatis {ex tuberculis externis). 

 Diam. aperturae 12 m. ; long, testse 300 m.

 The first spiral whorls are attached to a valve of a Balanus ; to- 

 wards the aperture is agglutinated a worn portion of a Venus, which 

 looks to be F. subimbricatus (Sow.), and a little bit of a Cardium, 

 which perhaps is C. senticosum (Sow.), both species from Panama, 

 which probably is the true locality, as it is of the variety. The sculp- 

 ture of this remarkable shell is very like that of Argonauta oryzata, 

 Meusch. ; like the latter shell, the tubercles outside form excava- 

 tions inside. This sculpture is, too, very like that of the young of 

 Stephopoma. The longitudinal liree become feebler towards the 

 aperture, in proportion to the size of the shell. The nodules are 

 often united in pairs by small transverse ridges, but never form 

 rings, as in the 



Var. a. ANNWLATUS. 



Tubus crassus, ponderosus, teres, aqualis, liris longitudinalibus 

 parum expressis tuberculiferis, interstitiis liris circiter tribus,
