Plate 16, figures 5-10 

 Genoholotype, Botellina lahyrinthica W. B. Carpenter 

 Botellina W. B. Carpenter, Proc. Roy. Soc. London, vol. 18, 1869, p. 444. 



Test generally cylindrical, sometimes branched, one end 

 rounded and swollen; wall arenaceous, whole test labyrinthic 

 with a common tubular chamber through the length of the test. 



Recent. Atlantic. 



Genus JULLIENELLA Schlumberger, 1890 



Plate 16, figures 11-14 



Genoholotype, Jullienella foetida Schlumberger 

 Jrillicnella SCHLUMBERGER, Mem. Soc. Zool. France, vol. 3, 1890, p. 213. 



Large, early portion of the test obscure, later spreading in a 

 flattened irregular manner with the periphery ending in simple 

 or branched processes; wall arenaceous, interior with tubular 

 openings, the interior somewhat labyrinthic. 



Recent. Coast of Africa (Liberia). 



The genera included in this family are very peculiar in their 

 characters, of rather large size, giving indications of being some- 

 what attached to the substratum on which they live. They are 

 very limited in their known distribution, but are usually very 

 abundant where found. Their relationships are not at all clear. 



FAMILY 15. SILICINIDAE 



Test usually planispiral, consisting of a proloculum and long 

 closely coiled tubular second chamber either undivided or par- 

 tially divided into chamberlets, the flattened sides building up 

 masses of secondary shell material ; wall arenaceous, usually 

 siliceous, sometimes partially calcareous ; aperture at the end of 

 the tubular chamber or the open end of the last-formed chamber 

 where division occurs.
