The difference between the slender N. pyrida and the more 

 compact N. soluta, is only one of degree, and that chiefly in the 

 length and thickness of the stoloniferous tubes. In the original 

 figures by Reuss these are almost as long and as slender as in 

 N. pyrula, and one of the examples figured has the later chambers 

 only connected by the tube, which, as before mentioned, is a 

 common feature in N. hispida. 



In the Malay Archipelago i\T. soluta is of great rarity and has 

 been observed only in Area 1.

N. capitata, as interpreted by Reuss and other authors, seems 

 to be nothing more nor less than N. soluta with the sutures or 

 base of the chambers costate or plicate. N. capitata, when so 

 named, is always figured as a test with few chambers, the initial 

 one being larger than those which immediately succeed it ; but 

 there is another form composed of numerous chambers ami 

 tapering almost to a point at the base. This is well represented 

 by one of Soldani's figures, to which d'Orbigny has given the 

 name of Dentalina acimlata* This form also has the con-
