Trochammina rohertsoni, n. sp. 



Test free, planospiral, involute ; discoidal, or compressed, nearly 

 symmetrical bilaterally, more or less excavated at the umbilicus ; peri- 

 pheral edge rounded, lobulate ; each convolution completely or almost 

 completely enclosing that preceding it; segments somewhat inflated, 

 usually five (four to six) in the outermost whorl : colour rich light 

 brown, texture very finely arenaceous, surface polished. Diameter about 

 yi^th inch (0-25 millim.). 



This prettly little Trochammina has long been familiar to those 

 who have been in the habit of examining dredged material from the west 

 coast of Scotland. I have before me drawings made nearly twenty years 

 ago from Hebrides specimens, and it has since been repeatedly brought 

 under my notice by the Eev. Dr. Norman and Mr. Robertson. It is very 

 distinct from any of its congeners, and I have ventured to associate with 

 it the name of my indefatigable friend who has done so much to elucidate 

 the marine invertebrata of the Clyde region. The species is not un- 

 common in deepish water on the west of Scotland, and it occurs also in 

 Mr. Wright's dredgings from the south-west of Ireland. I have placed 

 a mounting of it, under its present name, in the British collection at the 

 British Museum.
