66 DISCOVERY REPORTS 



Norman tells us that his specimen was picked out by Brady from 'Porcupine' 

 material, off Rockall, 1215 fathoms, and sent to him by the finder as a "sponge ? ", and 

 that Brady would not accept it as a Foraminifer. Later, Brady appears to have altered 

 his views, and there may have been some personal feeling over the matter, for he refers 

 to Norman's diagnosis as the description of a specimen rather than of a species, and 

 adopted Norman's name for a very different organism found at Challenger St. 344, off 

 Ascension Island. 



It seems probable that Norman's type was merely an abnormal specimen of T. 

 legiimen, from which it differs only in its flask shape. It has otherwise all the characters 

 of the earlier species. The type is in the British Museum, and the projecting spicules 

 referred to in Norman's description are by no means so conspicuous a feature as his 

 figure suggests. 



Brady's organism is much more roughly constructed ; local material, whether sand or 

 sponge spicules, is employed, and there is no evidence whatever of the definite selection 

 of suitable spicules for a particular purpose, such as is found in T. legumen and T. melo, 

 Norman. On the contrary, fragmentary spicules only appear to be used, and they are 

 roughly assembled. It is not surprising therefore that Rhumbler (vide Wiesner ut supra) 

 was inclined to assign the ' Gauss ' specimens to the genus Saccammina, under the name 

 S. ovum. I have not followed Rhumbler's view for the reason that Saccammina is such 

 a well-defined genus, and none of the Discovery specimens shows any tendency to the 

 formation of that distinct neck for the aperture which marks Saccammina. 



Technitella bradyi is evidently a much more widely distributed organism than T. melo, 

 which, so far as can be judged from published figures, appears to be known only from the 

 original locality, off Rockall, 121 5 fathoms. The figured records of T. bradyi (under the 

 name T. melo) are few, but give a range from the tropical Atlantic (Challenger St. 344, 

 off Ascension Island) to the Antarctic (Kaiser Wilhelm's Land). There are several 

 unillustrated records of T. melo, but without examination of the specimens it 

 cannot be stated whether they are of Norman's or Brady's type. Incidentally, and for 

 purposes of correction, it may be recorded that the specimens figured as T. melo by 

 Heron-Allen and Earland (H.-A. and E. 1909, TNS, p. 409, pi. xxxiv, fig. 9) were 

 subsequently used by them as the types of Nouria harrisii (H.-A. and E. 1914, etc., 

 FKA, 19 14, p. 376, pi. xxxvii, figs. 16-20). 



Technitella bradyi is of frequent occurrence at St. WS 482 in the Bransfield Strait, 

 o-ioo m., and the specimens show great diversity of size and shape, and in the per- 

 centage of spicules employed. Three specimens were found at St. 175, also in the 

 Bransfield Strait, 200 m., two of which were mainly of spicular construction, and the 

 other entirely built of sand grains. One good specimen at St. 170, off Clarence Island, 

 342 m.
