Eecent and fossil ; the recent specimens occurring in the 

 usual profusion, and the fossil specimens being very few in 

 number. 



Millett's record, " rare." 



32. Massilina secans var. tenuistriata Earland. 



Massilina secans var. tenuistriata Earland, 1905, Journ. Quekett Micr. Club, 

 ser. 2, vol. ix. No. 57, p. 198, pi. xi. fig. 5. 



A few specimens of this variety have been observed. It w T as 

 originally recorded from the immediate neighbourhood of Bognor. 



Note. — As usually is the case where a species predominates in 

 a shore-gathering to such an extent as does M. secans at Selsey and 

 at Bognor, abnormal and monstrous forms are of frequent occur- 

 rence. They have, however, no special value, beyond affording an 

 excellent illustration of the extreme possible variability of form, 

 which has fostered the multiplication of specific names to an extent 

 which is, in the opinion of many rhizopodists, to be greatly de- 

 plored. 



Sub-family 3. Hauerininae. 

 Articulina d'Orbigny. 



33. Articulina foveolata sp. n. Plate XV. fig. 8. 



Test elongate, compressed, spathulate, margin somewhat 

 rounded, sutures slightly constricted. Surface covered with 

 rounded shallow pittings arranged in fairly regular lines. 



This may be regarded as a close ally of Articulina lineata 

 Brady from which it differs principally in the nature of its 

 surface markings. 



One specimen only, a fossil, somewhat imperfect. Length of 

 fragment 0-850 mm. Breadth 0-3 mm.
