only the small male o£ a species o£ Pseudione. The Munida, we find, is also 

 infested by a Rhizocephalan parasite, the Triangulus munidce o£ Geoffrey 

 Smith * — probably a new record for the British fauna. 



(7) Miss L. B,. Thornely, who has examined and identified the Polyzoa 

 collected on the cruise, reports to me a list of 52 species, some of which 

 are of considerable interest — one (Miicronella ahyssicold) haying been 

 preyiously recorded from the Shetland Seas only. Our specimen was 

 obtained from the Minch, off the west coast of Skye. Leprcdia polita and 

 Idmonea atlantica are also worthy of note. 



(8) Knowing that Mr. E. Heron-Allen and Mr. A. Earland were engaged 

 on a ' Monograph of the British Foraminifera,' it occurred to me when 

 arranging the work of this cruise, that samples of our dredged deposits might 

 possibly fill some gaps in their list of localities. 



Mr. Heron-Allen supplied us with two dozen canyas bags which were duly 

 filled with fair samples of the unwashed mud, sand, or other material as it 

 was emptied from the dredge on to the deck. 



These samples are now being examined, and Messrs, Heron-Allen and 

 Earland report as follows in regard to them : — 



" It has been a matter of great satisfaction to us that we haye been 

 entrusted with this series of samples. Apart from any intrinsic merit or 

 interest which they possess in themselyes, they greatly enrich, and fill 

 gaps in, the collection of material already at our disposal from these seas, 

 linking up as they do the 'Goldseeker' dredgings with the work of 

 Messrs. Balkwill and Millett in the Galway District, our own in the Clare 

 Island District, and that of Mr. G. Wright on the ' Helga ' and other 

 dredgings off the west and south-west of Ireland. 



" So far, four bags of material haye been examined, with results at once 

 satis factor}^ and surprising. Indeed, whether the material is a shore-sand or 

 a dredged mud, Miss Catherine Herdman, to whom we understand we owe the 

 collection of the samples, seems to have displayed an unerring instinct for 

 those muds and sands which were exceptionally rich in quantity of specimens 

 and quality of species. 



" In Sample No. 1 (At anchor, Lowlandman's Bay, Jura, 5 f ms.), in addition 

 to a series of 20 species of the genus Lagena, we have found the family of 

 the Textularidse very finely represented, the otherwise dominant form being a 

 robust and highly papillate Rotcdia of the heccarii type, attaining remarkable 

 dimensions in enormous quantities. The Station yielded 89 species. 



"Sample No. 2 (Dredging, Sound of Mull, 20 fms.), which reached us as a 

 cake of hard black mud, 254 c.c. in bulk, became on the sieve 5 c.c. of fine 

 material, which yielded 107 species. The dominant feature of the dredging 



* This specimen has since been examined by Mr. Geoffrey Smith, who finds that this 

 fresh material enables him to correct the description in his Naples Monograph and to show 

 that these parasites of Munida should be included in the genus Lernceodiscus, the other 

 members of which are also parasitic on the GalatheidjB.
