"HUXLEY" FROM NOKTII SIDE OF THE BAY OF BISCAY, AUGUST, 190(5. 11 



Station XIII. Lat. N. 48" 7'. Long. W. 8'' 13'. 412 fathoms. 



There are six specimens in the collection, varying in length from 

 225 mm. to 325 mm. The species was obtained by the Caudan in 

 1220 metres.

This species was originally found by the Challenger in 1900 fathoms 

 off Monte Video, but it was subsequently discovered by the Caudan at 

 Station XVL, 5° 53' W., 45° 38' N., in 1220 metres. 



The specimen is broken at the base, and is about 530 mm. in total 

 length. The lateral branches arise sometimes in pairs, sometimes 

 alternately, sometimes irregularly, from a strip of about one-third the 

 width of the total circumference of the main axis, and are in two 

 series, inclined at an angle of about 30° to each other. The lateral 

 branches in the middle region are 250 mm. in length, those at the 

 distal end very much shorter. At the proximal end the branches are 

 broken. 



The zooids seem to be about the same size as the type specimen, 

 that is about 3 mm. in a diameter transverse to the axis, but the 

 tentacles are much more contracted than those of the Challenger 

 specimen, and are not more than 3 mm. in length (cf. 4-7 mm. in 

 the type). 



The character of the spines on the axes corresponds with the descrip- 

 tion of the type. Although there is a difference in the manner in 

 which the lateral branches arise from the main stem between the 

 Huxley and Challenger specimens, there is no good reason, in my opinion, 

 for regarding them as distinct species. 



The species was also found in the Bay of Biscay in 1220 metres by 

 the Caudan.
