470 Mr. H. J. Carter on Deep-sea 



it than that it was about the size of that above mentioned, but 

 had no heard, and an »;«tufted even surface without any trace 

 of barbed spicules, but with the usual triradiates and the large 

 acerates above mentioned, which, when entire, must have 

 given it somewhat of the character of Ute capillosa, Sdt. 

 (Spongienf. Adriat. 1862, Taf. 1. fig. 6). 



Since the above was written and illustrated, I have seen 

 Franz Eilhard Schulze's paper on the structure and develop- 

 ment of Sycandra raphanus, Hjickel (Zcitschrift f. wissensch. 

 Zoologie, XXV. Bd., 3. Supp., Dec. 1875), in which four figures 

 are given like the spined spicules above mentioned in the 

 Budleigh-Salterton specimens commonly called " Grantia 

 ciliata " (Taf. xix. fig. 1, «-(/), also said to be " rare " and 

 occm-ring in the tufts at " the distal ends of the radiating 

 tubes." 



Addendum. 



Having made a Table of all the sponges dredged up on 

 board H.M.S. ' Porcupine ' in 1869-70 that Avere handed over 

 to me, with the stations and depths respectively from which 

 they had been obtained, I have been able to draw up the fol- 

 lowing summary so far as the information accompanying them 

 permits, viz.* : — 



1st. In the Deep Sea heticeen the North of Scotland, the Orkneys, 

 the Shetland and the Faroe Islands.

 classification, as far as is at present possible, no notice is to be taken of 

 tbe same name being repeated bere and tbere, as tbis refers to tbe

 cation.
