This is one of an aberrant group of Lingulinos in which the 

 chambers, in place of being equitant as in the type, are connected 

 by stoloniferous tubes of more or less slenderness. The test is 

 composed of two or more lageniform chambers arranged in a linear 

 series, the primordial chamber being of a character different from 

 the others. 



One of this group was described and figured by Dr. Chester 

 under the name of L. licrclmani* This was a solitary specimen 

 from shore mud at Southport. 



In one of the examples of L. carinata figured by Brady f the 

 primordial chamber is armed with a pair of marginal spines at the 

 oral end. 



Amongst the abnormal forms of Nodosaria radicula figured by 

 Haeusler, two bear a resemblance to this group of Lingulina.% 



From my friend Mr. H. Sidebottom, of Cheadle Hulme, I have 

 specimens and drawings of a form closely allied to L. limbata, but 

 not identical. Of this he writes, "About 150 specimens were 

 found in the material from off the coast of the Island of Delos 

 (Grecian Archipelago), depth 8 to 14 fathoms, by my brother- 

 in-law Mr. C. H. Nevill and myself. In six cases there is a 

 third chamber similar to the second, only rather larger. The 

 species occurs at other parts of the Mediterranean very rarely, 

 also from the Seychelles Islands." 



L. limbata is very rare in the Malay Archipelago, and has been 

 found only at Station 6 in Area 1. 



Lingulina pagoda sp. n., plate XI. figs. 16, 17. 



Test linear. Primordial chamber flask-shaped with longi- 

 tudinal costse. Succeeding chambers pyriform, compressed, broad 

 at the base, which is encircled by a tubuliferous fringe. Aperture 

 oval, in a phialine neck. Length ■ 50 mm. 



This curious form may be said to be compounded of an initial 

 cell resembling Lagena sulcata, from which proceeds a series of 

 cells each of which has somewhat of the characters of L. Jtmbriata, 

 the base of each being attached to the phialine neck of the pre- 

 ceding, and each successive chamber increasing slightly in size. 



This form also is very rare in the Malay Archipelago, and has 

 been observed only at Station 6 in Area 1. 



Fig. 18 represents a detached chamber found at Station 30 in 

 Area 2, which indicates a species distinct from those described. 

 The length of the chamber is 0-15 mm.
