THE IRISH SEA. 119 



tris and Asterias Johnstoni* of British authors, but is 

 very distinct from those species. It is the "A. eques- 

 trisV of Templeton (Mag. of Nat. Hist. vol. ix. p. 237), 

 and has been named after that naturalist by my distin- 

 guished friend, Wm. Thomson, Esq. of Belfast. Dr Cold- 

 stream has found it in Bute.

 nal, flat, thin, covered above and beneath with fascicu-

1. PALMIPES MEMBRANACEUS.f 



Body pentagonal, above white, with five red rays and a red bor- 

 der, entirely covered above with small rounded tubercles, bearing 

 bundles of minute spines. Spinous tubercles most numerous, and 

 scattered in the red rays and margin, arranged in regular rows on 

 the white portion. Beneath the tubercles are elongated and ridge- 

 shaped, and are arranged in a similar manner. Avenues bordered 

 by longitudinal fasciculi of larger spines ; those immediately around 

 the mouth most developed. Madriporiform tubercle small, flat, 

 striated, subcentral. 



Frequent in deep water on the Manx coast. The largest specimen 

 I ever took measured five inches across.

 Link.) — Body pentagonal, gibbous, thick, covered above 

 and below with short spines ; avenues bordered by a row 

 of spines ; suckers biserial. — PI. III. Fig. 4. 



• This name must be changed. There is an Asterias Jonstoni (allied 

 to A. aurantiaca) described and figured by Delia Chiagi. Memorie, vol. 

 ii. p. 356. It is the "A. auranliaca" 1 var. 2, of Lamarck.
