1898— 1902. No. 20.) - BRACHIOPODS AND MOLLUSCS. 43 
Cucumaria minuta, Fasricius. 
Locality: 
July 14. 1902. St. Helena: 4—14 m. Lange and eal stones overgrown with fuca- 
ceae. One 7 mm. long contracted specimen. 
Papillae are arranged in single rows, the three ventral rows having 
7—9 papillae. Skin is rough. When looked at under the microscope 
it will be found to be thickly covered with larger and smaller irregular 
nearly round calcareous plates which, as Lirken? says, remind one of 
the calcareous plates of cucumaria assimilis? depicted by Dien and 
Koren. The specimen preserved in alcohol is of a white colour. 
The specimen seems to agree most closely with the West Green- 
land cucumaria (holothuria) minuta, Fasricius® which is said to have 
three rows of papillae more developed than the two others, and its skin 
abundantly furnished with calcareous plates. I have accordingly referred 
it to this species. It must be stated, however, that it has not been 
possible to make a complete examination of the specimen, as I have 
not been able to dissect it 
Cucumaria minuta has not been previously found i in the archi- 
pelago north of America. Besides the west coast of Greenland it is 
known to occur on Grand Manan (North America), at Spitzbergen and 
on the Murman Coast. In the western hemisphere it was previously 
known to be distributed between 44° and 69° N. Lat., whereas its nor- 
therly limit is now 76° 15.5’ N. Lat. In the eastern hemisphere it is 
distributed: between 68° and 80° N. Lat. From east to west it was pre- 
viously known to occur between 44° E. Long. and 67° W. Long., or 
throughout 108 degrees of longitude. (Cf. Lupwie: Arktische und sub- 
arktische Holothurien 4). It is now known to be distributed westwards 
as far as 89° 16.5’ W. Long., or throughout about 130 degrees of 
longitude.
