252 SIPHONARIA SIPHO. 



NOTE XXXII. 



ON A PECULIAR MODE OF ATTACHING OF 

 SIPHONARIA SIPHO, SOW. 



Dr. J. H. VERNHOÜT. 



Lately the Leyden Museum received from Prof. K. Mar- 

 tin some specimens of Siphofiana sipho Sow., collected by 

 himself at Batoe Kapal on the eastcoast of Hoeamoeal, a 

 peninsula of the island of Ceram, one of the Molucca's. 

 Now it is not to be wondered at, that this species, widely 

 distributed in the Molucca's, was also found in the quoted 

 locality; but an observation about its mode of attaching, 

 made by Prof. Martin, who communicated it to me, and 

 kindly allowed me to publish it, seems to be very remarkable. 



On a piece of „Glimmerschiefer" (n'^ 389 of Prof. Mar- 

 tin's collection) he observed some small specimens of Si- 

 phonaria sipho, attached with their apices to the stone, 

 so as to form little cups. Prof. Martin himself loosened 

 the shells and took the soft parts out of them. The apices 

 of the shells show no characters different from those of 

 other shells of this species in our collection. 



No other example of a limpet-like mollusc, having been 

 found attached on this manner, being known to me, I 

 mention it. Perhaps other naturalists might have observed 

 similar facts; in that case they should oblige me, if they 

 bring them to my notice.
