formed coil, broad an 1 low, sutures very slightly depressed; wall 

 arenaceous, somewhat roughened, usually smooth wuthiii; aperture 

 a more or less elongated, curved slit at the base of the apertural 

 face of the cham))er, simple; color gray or ))r()wn. 



Diameter, 1-2.5 mm. 



Dlstrlhutlon. — This s])ecies is common in the colder waters of 

 the Atlantic coast,' but is less so in the warmer waters of the Guif 

 of Mexico and Caribbean Sea. The -30 C/iallenger stations in 

 the Atlantic cover the whole area. It is common on the northern 

 and eastern coasts of Europe and known from the colder waters of 

 Franz Josef Land, Spitzbergen, and Baffins Bay. The Scot' a 

 material from tlie Antarctic had this species at nine stations as 

 recorded by Pearcey. 



The reason for using //. suhglohosa Sars instead of //. latidorsatum 

 Bornemann has been discussed in an earlier paper.' 



By many writers this specific name has been used to include the 

 species here known as Cribrostomoides hradyi so that the distribution 

 of the two should be checked where possible. Crihrostomoides may 

 be easily distinguished in the adult by the row of pores forming the 

 aperture while the aperture of //. suhgJohosum is always simple. 



The slight departure of the last coil from the true planospiral form 

 is often characteristic.
