N° 17. 13 August 1884. Near the black and white striped 

 buoy (Longnose) oö Margate. At 7 o'clock in the morning. The 

 large dredge came up crooked , the net was torn in consequence 

 of the irregularities of the rocky bottom. Of the small dredge the 

 arms only were hoisted in. Bottom : sand with stones and lumps 

 of chalk. Depth 10 fathoms. Temperature of the water: 18°5 C. 

 The following animals were caught: 



Echinus, Ophiothrix , Galathea intermedia a ), Porcellana longi- 

 cornis , Pagurus , Palaemon , Pandalus brevirostris , Pilumnus hir- 

 tellus , Stenorhynchus , Amphipoda 2 ) , Nymphon sp. , Trochus , 

 Pecten, Aeolis , etc. 



The two specimens of Nymphon hirtum that were taken at this 

 place are both males. They resem ble in every respect the specimen 

 studied, describecl and figured by G. O. Sars — perhaps they are 

 slightly less hairy. The length of the specimen I figured (Fig. 14) 

 is 6 mm. when measured with the proboscis; the false legs are as 

 long as the body, the ambulatory legs are slightly more than three 

 times as long as the body. The shape and the armature of the last 

 two joints is very characteristic and may be judged of from the figure. 



Like Nymphon gracile , Leach, which is a very common inha- 

 bitant of the Dutch and English coasts, living there in very shallow 

 water, and is now known to occur also in the Barents Sea, off 

 Cape Russky Saworat , so the Chaetonymphon hirtum , which lives 

 near Iceland and Norway (at about 70° Lat. N.) has the same 

 southern distribution , being recorded now also from near the 

 entrance of the river Thames at 51° 22' Lat. N. 



No special attention has been paid of late, at least so far as 

 I know of, to the animals of this group inhabiting the North 

 Sea, the English coast, etc. Several of the species described by 

 G. O. Sars for the northern part of the North Atlantic, as also 

 for the coast of Norway , may be found to have a much more 

 southern distribution than has been supposed hitherto. 



1) This species figures as Munida in the Report. 



2) Melïta obtusata, Montague sp., Aora gracilis, Sp. Bate, Gammaropsis erytroph- 

 t kalmus , Lilljeb. and others.
