A few examples of the above species were seen in the washings, 

 but owing to their resembhng the sand particles in colour, and the 

 absence of any very definite shape, they are easily overlooked. The 

 first recorded specimens came from the Bargate Beds of Lower 

 Greensand age, near Dorking, in Surrey, and the species was sub- 

 sequently found both in the black and brown Ehgetic clays of Wed- 

 more, in Somerset, England. Dr. Egger's specimens came from 

 the Cretaceous marl of the Upper Bavarian Alps ; they are referred 

 to II. fontinense, but that species is evolute in the earlier spiral 

 chambers, whilst the Cretaceous specimens are involute.

Specific Gharaclcrs. — Test very thin, diaphanous ; subcircular to 

 subelhptical. Sutures nearly straight, fairly well marked, but seg- 

 ments more clearly seen when the test is moistened ; about six 

 segments visible. Test white, composed of fine silicious particles. 

 Surface fairly smooth. Largest diameter about 1 mm. ; width 

 •6 mm. ; thickness "05 mm. 



This species recalls the minute Baplophragmiamterqucmi-'- found 

 in the French and English Gault and the Cretaceous marl of the
