Of the smaller Diplommatina T have three lots before me, No. 

 1, collected i>y Mr. Masters on Ijord Howe, from which the 

 example figured was selected ; No. 2, collected by the expedition 

 on Lord Howe ; No. 3, collected by the expedition on Rabbit 

 Island. These range in length from 3i (No. 1) to 4^ mill. (No. 2) 

 in length. Some individuals are more closely costulate than 

 others, .sometimes the ultimate, sometimes the penultimate whorl 

 is the most densely ribbed ; the coloration varies from light yellow 

 to pale purple, and some specimens are considerably narrower 

 than others. Though none correspond to Pfeift'er's description of 

 chordata, this instability of character inclines me to suppo.se that 

 a larger collection from diflerent parts of the island would supply 

 links to connect that species with capiUacen. Indeed the large 

 form macgitlivrayi may also prove but an extreme variation of 

 the same type.* 



* Dr. .Macilonald ha.^ figured (Ann. Mag. Nat. Hist. (4), iv. pi. 4, fig. 9) 

 the radii la of one of the Lord Howe Diploramatinte, which onebedoea
