The bulk of the collections consists of: sessile organisms 

 that were actually attached to the cables, and among these 

 the barnacles are conspicuous by their numbers and, in many 

 cases, by their large size. One of the specimens of Scalpellum 

 >//'/li/)es mentioned below is among the largest of the pedun- 

 culate Cirripedes yet recorded. 



While some species of deep-sea Cirripedes are known to 

 have a very wide distribution, occurring in the Atlantic, the 

 Indian, and the Pacific Oceans, there is some evidence that 

 certain species are confined to more restricted habitats. 

 Thus, two of the species recorded below (S. nudipes and 

 S. persona) have been only very recently described by 

 Dr. Annandale from localities not far distant, and probably, 

 indeed, from another part of the same cable. 



The " new species" that are described here, like many of 

 those already established in the genus Scalpellum, must not 

 be taken too seriously. A large proportion of the known 

 species of the genus have been described from solitary 

 specimens or from a very few, and we are without the means 

 for forming even the roughest estimate of the limits within 

 which variation may occur. Further, even where a con- 

 siderable number of specimens have been found growing 

 side by side or attached to one another (as in the group of 

 S. bengalense mentioned below), there is reason to believe 

 that they may all belong to a single family, and that the 

 uniformity of character which they show may be, in part, 

 fraternal or filial rather than specific. At the same time
