106 BRITISH SPONGIAD^. 



(1869, station 54) between the North of Scotland and 

 the Faroe Islands, in 363 fathoms {fide Carter), Car- 

 ter's variety hulbosa was dredged (" Porcupine," 1870, 

 stations 24, 25) near Cape St. Vincent, on the Spanish 

 Coast, in 292 — 374 fathoms. The form seems almost 

 intermediate between H. forceps and Desmacidon ancejas, 

 Schmidt.* It agrees with the latter in having the legs 

 of the forcepiform spicules short, strongly divergent 

 and bulbous at their terminations, but in Desmacidon 

 anceps only one of the ends is thus bulbous, while the 

 anchorates are quite different, being equi- and not 

 inequi-anchorates, and the other spioula also differ. I 

 am inchned to think that the Spanish sponge differs 

 specifically from M. forceps. Should this hereafter 

 prove to be the case Mr. Carter's varietal name can be 

 most appropriately retained as the specific.
