Anthoptilum murrayi, Kolliker. N. Atlantic, S. of Halifax (Challenger) ; E. coast 



of N. America (Verrill); Bay of Gascony, S. of Iceland (Jungersen). 

 Funiculina quadrangularis (\\i\\nx) = Leptoptilum gracile, Kolliker. New 



Zealand, as L. gracile (Challenger) ; as /'. quadrcmgvloru, North Sea, 



Atlantic Ocean, European and American sides, Mediterranean, eta 

 Pavonaria willemoesii (Kolliker) = Microptilum willemoesii, Kolliker. As .17. 



ivillemoesii from south of Yeddo (Challenger). 



Among the new facts of distribution, perhaps the following are of most inteiv-t : 

 Stachyodes allmani, Wright and Studer. From the Laccadive Sea (Investigator) ; 



previously from the reefs, Fiji. 

 Callistephanus koreni, Wright and Studer. From the Andaman Sea (Investigator) ; 



previously from off Ascension. 

 Juncella elongata, Pallas. From the Bay of Bengal (Investigator) ; previously 



from Atlantic, West Indies, N.E. coast of Australia, and Algoa Bay. 

 Distichoptilum gracile, Verrill. From Investigator Station 231, 7 34' 30" N., 



76 08' 23" E., and 321, 5 4' 8| N., 80 22' E. ; previously from North 



Atlantic, S.W. of Nantucket Island, etc. 

 Umbellula durissima, Kolliker. From Laccadives ( Investigator) ; previously from 



S. of Yeddo and Antarctic. 

 Anthoptilum murrayi, Kolliker. From Investigator Station 104, 11 12' 47" N., 



74 25' 30" E. ; previously from N. Atlantic, Bay of Gascony, S. of 



Iceland. 

 Funiculina l quadrangularis (Pallas) = Leptoptilum gracile, Kolliker. From 



Bay of Bengal (" Investigator "), as Leptoptilum gracile, and previously from 



New Zealand. F. quadrangularis, previously from North Sea, Atlantic, 



Mediterranean, etc. 

 Pavonaria 1 willemoesii ( Kolliker ) = Microptilum willemoesii, Kolliker. From 



Andaman Sea ; previously as M. willemoesii from Japan. 

 The wide distribution of some deep-sea types is thus well illustrated. 



Some Matters of Detail. 



It may be convenient to direct attention here to some matters of detail that 

 are of general interest. 



The siliceous axis which forms the support of Sarcophytum aberrans, n. sp., 

 is 300 mm. in length by 2-3 mm. in breadth, and is probably the huge spicule of 

 Monorhaphis or some allied sponge. (See Plate I. fig. 2c.) 



Analogous, on a smaller scale, is the siliceous spouge-spicule, which servc< 

 as a support for Sympodium incrastcms, n. sp. (See Plate II. fig. 7.) 



1 It is possible that our Funiculina quadrangularis is the young form of some other species of 

 Funiculina, and that our Pavonaria mllemoeni is the young form of some alivaily known species of 

 Pavonaria.
