240 Mr. A. G. Butler on a Collection of 



Thorsliaven in the Faroe Islands, and the Haaf banks on the 

 east of Shetland ; also in jar No. 25 = 374 of 1870, near Cape 

 St. Vincent. The finest and most perfect specimens that I have 

 ever seen are those from the Haaf banks, presented to the 

 British Museum by Dr. Bowerbank. 



Phakellia (Bk.) infundibuliformis, G.^=HaUchondria inf.^ 

 Johnston. 



Entire specimens and fragments of this sponge appear in 

 jars 65, 78, and 83, which, being the numbers of the stations 

 where they were respectively dredged up, indicate a depth 

 varying from 290 to 345 fathoms, with a locality between the 

 Orkney, the Shetland, and the Faroe Islands. 



This sponge in general form is very like, although much 

 inferior in size to, Phakellia ventilahrum — indeed just as 

 Johnston has described it ; and I can see no reason for alter- 

 ing any thing but Johnston's generic name to " Phakellia^'' 

 and not to " Isodictya " as Dr. Bowerbank has done. The 

 spicules are essentially those of Phakellia ventilahrum^ viz. 

 an acuate and an acerate ; but they are shorter, stouter, and 

 straighter than those of the latter, the acerate being simply 

 curved, and not undulating as in P. ventilahrum. Outlines 

 of two specimens of P. infundihuliformis in its fan-shaped form 

 may be seen in situ on the pebble on which they have grown 

 (PLXILfig. 1,///).

XXI. — On a Collection of Leiyidojpterafrom Port Moresby^ 

 New Guinea. By Arthue G. Butler, F.L.S. &c. 



The following species were recently received from Mr. W. 

 y . Turner of the London Medical Mission at New Guinea, and 

 form a very interesting little collection. Most of the named 

 species were previously known from Aru, only one or two of 

 the commoner and more widely ranging species being identical 

 with those of Australia.
