SQUAMULINA LAEVIS Schultze 



There is an Atlantic record for this species given by Siddall," 

 " Colwyn Bay, on Zoophytes, very rare." The types were from 

 Ancona. 



Under this genus Carter described two species from the " Beach 

 at Budleigh — Salterton, Devonshire; cast ashore by storms." These 

 were attached to algae. They are Squamulina scopula Carter ^^ and 

 S. varians Carter.'* It is very doubtful if either of these has any 

 affinities with Squamulina. 



Family 18. FISCHERINIDAE 



Test coiled, earHer ones somewhat planispiral, later ones trochoid, 

 all coils visible from the dorsal side only, the last-formed one from 

 the ventral side; chambers distinct but not inflated, usually four or 

 five making up the last-formed coil; wall calcareous, imperforate; 

 aperture rounded, formed by the open end of the last-formed 

 chamber. 



This family represented by the single genus Fischerina represents 



the attempt in fairly recent times of the assuming of a trochoid form. 



It is surprising that this trochoid form taken on by many groups has 



never been successfully tried out by the vitreous or porcellaneous 



groups.

 No. 1, Cushman Lab. Foram. Res., 1928, p. 170. 



Test coiled in a low conical spiral; chambers few in each coil, all 

 visible from the dorsal side, only those of the last-formed coil from 

 the ventral side; wall calcareous, imperforate; aperture formed by 

 the open end of the last-formed chamber, simple. 



Pliocene to Recent. 



The species of this genus are mostly confined to shallow warm 

 water of the Tropics.
