This variety with the rounded base is almost as abundant as 

 the foregoing, and is just as evenly distributed. The aperture 

 likewise is often entosolenian, but there is not quite so much 

 variation in the form of the test. 



In treating of the fauna of an extensive region it is hardly 

 desirable to enter into the controversy with regard to the dual 

 forms, and it must be left to other investigators to determine if 

 G. laevigata and G. rotundata are respectively the microspheric and 

 megalospheric states of the same species, but it may be pointed 

 out that their almost equal abundance in the Malay Archipelago 

 is rather against the theory. 



Nodosaria (Glandidina) echinata sp. n., plate XL fig. 4. 



Test subovate ; broadest near the centre and tapering towards 

 each end, the base being either acute or rounded. Sutures indis- 

 tinct. Aperture situated in a short neck with an everted lip. 

 Surface of the shell beset with minute spines which are longest at 

 the primordial end of the test. Length ■ 38 mm. 



This may be described as a spinous variety of both N. laevigata 

 and N rotundata. In the present state of uncertainty as to the 

 nature of the relations between the Nodosaria? differing in character 

 only in having the base either acute or rounded, it is here con- 

 sidered inadvisable to follow the hitherto accepted rule of treating 

 the two forms as representing different species, and giving them 

 distinctive names, consequently the more simple course has been 

 adopted of associating them under one heading. 



Their intimate relationship is shown by their both possessing 

 the phialine aperture, which is an unusual feature in Glanduliim . 



There are numerous examples of a variety of N. laevigata, in 

 which the spines are confined to the base. This form has the 

 aperture invariably mammillate with radiating stripe ; and the base 

 is always acute or apiculate. 



The three spinous varieties here described are by no means 

 uncommon in the Malay Archipelago, being found at several 

 Stations in both Areas and are about equal in number.
