Generally distributed, hut does not occur after Station 36 till we reach the 

 extreme south at Station 55. Usually abundant and often very variable. The 

 coarsely costate type, on the whole, predominates, but at the most representative 

 Stations 16, 18 and 36, both coarsely and finely marked types occur in company. 

 In tlie deep-water Stations the coarsely costate form often accpiires extensive 

 wing-like development of the co.stae.

Very rare except at Station 16, where a numlier of magnificent specimens 

 were found rivalling even Haeckels remarkable figure in beauty (Kunstformen 

 der Natur, Leipzig, 1899. Pl. Ixxxi, fig. 10). The sjjaces between the tubulated 

 wings are sometimes smooth, but at others more or less strongly sulcate.

Stations 6, 7, 11, 31. 



Few records and the specimens rare, but varying greatly in the development 

 of the ornament. At Station 6 the individuals are large, but the ornament 

 is confined to a small radiating star on the rounded base. At Station 7 the 

 specimens have very long necks Init weak costae, at Station 1 1 the costae are 

 raised almost into wings and the neck, which is very long, is strengthened with 

 a spiral band of shell - substance. At Station 31 a single neckless specimen, 

 globular, and covered as to its lower half with innumerable fine costae.
