7. Beania pulchella Livingstone. 



Beania pulchella Livingstone, 1929, p. 56, pi. i, fig. 15, text-fig. 1. 

 Station distribution. New Zealand: St. 934. 

 Geographical distribution. New Zealand (Livingstone; Discovery). 



The one small specimen of this species is without ovicells. On the whole it agrees 

 very closely with Livingstone's description, but the spines of the outer series distinctly 

 originate as branches from the bases of the spines of the inner series. The basal spine- 

 bearing processes are arranged in a single row along the median longitudinal line of the 

 zooecium. O'Donoghue and de Watteville (1935, p. 209) assumed from Livingstone's 

 description, which is perhaps ambiguous on this point, that the zooecia are arranged in 

 transverse rows in this species, but Livingstone's photograph and the present specimen 

 both show the usual alternation in which each zooecium is connected with six others. 

 The tubes are short and stout. The distal tube arises from the basal surface of the zo- 

 oecium at some distance (two-thirds to one-half the length of the zooecium) from the 

 distal end, and merges, without any recognizable point of transition from tube to 

 zooecium, into the distal zooecium. Although the zooecia thus overlap each other 

 considerably, they lie flat as in Livingstone's photograph. In B. hirtissima, where the 

 distal tube also originates at some distance from the distal end of the zooecium, the free 

 distal portions of the zooecia are more or less erect.

Geographical distribution. Mediterranean (Heller; Jullien; Waters; Harmer; Neviani; and 

 others); Cape Verde Islands (Jullien; Calvet); John Adams Bank, off Brazil (99.7.1.4674); 

 Magellanic Region (Jullien; Waters; Calvet; Discovery); Patagonian Shelf (Busk; Vallentin; U.S. 

 National Museum; Discovery); off Patagonian Shelf, down to 240 m. (Discovery); South Africa 

 (Jullien; Marcus; O'Donoghue; Hasenbank); Mauritius (Jullien); Marion Island; Prince Edward 

 Island (Discovery); Kerguelen (Busk; Kluge); Australia (MacGillivray; Waters; Harmer; Living- 

 stone); New Zealand (Waters; Livingstone); Auckland Island (01.12.26.33, Southern Cross Ex- 

 pedition); Japan (Jullien; Ortmann; Yanagi & Okada; Harmer). 



Extensive sheets of this species were taken at Port Stanley, Falkland Islands (St. 56) 

 on 19 May 1926, and in some pieces every zooecium is fertile. The fertile zooecia have 

 a shoulder on each side of the ovicell, but have no distal spines. The presence of ovicells 

 may account for the absence of spines in Hasenbank's fragment from South Africa. 



Records of this species from New Zealand have sometimes been based on specimens 

 of Beania bilaminata (Hincks). For example, those from Dr Lyell recorded by Busk 

 (18526, p. 54), and material sent to the British Museum by Hutton as B. magellanica
