AMATHIA LENDIGERA. 517 



Localities. Very generally distributed, but seems to 

 be less abundant in the north than in the south and west. 

 It is not recorded from Shetland ; nor does it occur in 

 the Scandinavian and Arctic lists. Northumberland and 

 Diu-ham, not rare (Alder) : Firth of Forth (D. Landsb., 

 jun.) : Filey, Yorkshire; Llandudno; Menai Straits; 

 Isle of Man, common; Swanage Bay, in profusion; Ilfra- 

 combe, tide-marks and 8-10 fathoms ; South Devon, in 

 great luxuriance, chiefly on Halidrys (T. H.) : Isle of 

 Wight (W. T) : Hastings, somewhat rare (Miss Jelly) : 

 Sussex, frequent (Pallas) : Tenby (F. Walker) : Cornwall 

 (C. W. P.) : north, east, and west coasts of Ireland (W. 

 T.) : Youghal (Miss Ball) . 



Geographical Distribution. Roscoff, at all depths, 

 especially on fibrous Algse in the Zostera-hediS, (Joliet) : 

 France, S.W. (Fischer) : coast of Belgium (Pallas) : Posi- 

 lipo, St. John's Grotto (Cavolini) : Adriatic, on Algaj and 

 zoophytes (Heller) : South Africa, the present species or 

 one closely resembling it (Busk). 



This pretty species is diffuse and luxuriant in its habit

 which it delights, with a perfect tangle of its delicate, 

 flexile stems. As Ellis has remarked, " it climbs up and 

 runs over other Corallines and Fucuses as Dodder does 

 over other plants.'' It is truly scandent in its habits, and 

 not only attaches itself by means of its slender inter- 

 twining branches, but also gives off here and there at 

 times, as the ivy does, delicate fibrils, Avhich seize the 

 nearest support, and secure, as it were, a new starting- 

 point for its vigorous growth. 



The zooecia, which form the isolated groups, are ranged 

 in two contiguous pai'allel rows, those in each roAv being 

 closely united to one another. They become gradually
