Although this species occurs in the Malay Archipelago in a variety 

 of forms aud with diverse surface orDainents in none of them are to 

 be found the two concentric circular costao characteristic of the 

 examples from the Eocene of the neighbourhood of Paris. 



The form which is most abundant is that with the faces covered 

 with minute dots, to which allusion has already been made in treating 

 of L. marginato-jierforata. 



L. bicarinata occurs at several Stations, but is most plentiful in 

 Area 2. 



It has been found fossil in the Eocene of Paris ; in the Tertiaric- 

 of St. Erth ; and in the Neogene of Italy. 



Lagena auriculata Brady, plate XIY. figs. 14, 15, 10. 



Lagena auriculata Brady, 1881, Quart. Journ. Micr. Sci., vol. 

 xxi. n.s. p. 01. L. auriculata Bradv, 1884. Cball. Kept., p. 487, 

 pi. lx. tigs. 29, 33, and? 31. 



As shown by Brady's figures, this is a very variable species, and 

 in the Malay Archipelago it occurs in mauy forms, ranging from a 

 smooth test similar to that of L. laevigata, with a small loop on either 

 side of the base, to the complex form with an extended neck, and 

 ' provided with a luxuriant tubulated wing. This latter variety i< 

 usually much contorted, as represented by fig. 14. The trifacial 

 variety is represented by fig. 10. 



Essentially a deep-water species; being found, according fco 

 Brady, at depths of from 1370 to 2740 fathoms in the North and 

 South Atlantic and South Pacific ; wdiilst off Gomera, Canaries, in 

 only 020 fathoms, the specimens were small and poorly developed. 

 In view of these facts it is interesting to note that the species i.-; 

 abundant and varied in the shallow waters of the Malay Archipelago. 

 and deficient only in size, being about one-half the length of the deep- 

 water examples. 



It occurs in more or less abundance at several Stations, and, like 

 several other species of Lagena, is most plentiful in Area 2. 



Lagena auadrangtdaris Brady, plate XIV. fig. 17. 



Lagena quadrangular is Brady, 1884, Cball. Kept., p. 4^3. 

 pi. cxiv. fig. 11. 



This is a very rare species, and has hitherto been found only at 

 Puune Island, Torres Strait. 155 fathoms.
