arachnids, or as an independent class — he was so good as to 

 collect these animals for me whenever he met with them. At 

 Bundoran only two individuals — one an adult male carrying 

 eggs — of a single species rewarded his search. On examin- 

 ation, these proved referable to a pj^cnogon from the Bay of 

 Naples described in Dr. Dohrn's great work' under the name 

 of Cloteiiia conirostris. The Rev. Canon A. M. Norman, f.r.s., 

 to whom I communicated the discovery, was so good as to 

 coniBrm my impression that both genus and species were new 

 to the British marine fauna ; and this opinion was corroborated 

 by Mr. W. T. Caiman of Dundee (who, in conjunction with 

 Prof. D'A. W. Thompson, has done much w^ork on the British 

 species), when, on a recent visit to Dublin, he examined the 

 specimens. This pycnogon, then, hitherto only known from 

 the Bay of Naples, but now recorded from Donegal Ba}^, will 

 form a most interesting addition to those Mediterranean 

 animals which range far northwards along our western coast. 

 One can hardly doubt that future search will reveal other 

 Irish localities further to the south. 



The genus Cloteyiia, founded by Dr. Dohrn in 1881 for the 

 single Neapolitan species C conirostris, differs from the large 

 genus Ammothea in its extremely compact and radially-formed 

 body, the segments of which are fused together (Plate 6, fig. 2), 

 and in the reduction of its chelifori (fig. 2, a) to minute knobs. 

 But the character on which Dr. Dohrn chiefly relied was the 

 presence in Clotenia of a genital opening on the second coxal 

 joint of each of the male's walking-legs except those of the 

 first pair, whereas in Ammothea, both the first and the second 

 pair in the male want these openings. But in 1879, Mr. Miers"" 

 had described an allied pantopod from off the far southern 

 island of Kerguelen under the name of Tanystyhim styligerum, 

 the genus being specially founded for this species ; and in 1880, 

 Prof. E. B. Wilson in his monograph of New England 

 pycnogons^ had referred to Tanystylum a species, T. orbiculare, 

 evidently very near indeed to Dr. Dohrn's Clotenia co7iirostris.
