MAEINE BIOLOGICAL STATION AT POET EEIN. 11 



One specimen of Modiolicola insignis, Aurivillius, new 

 to the district, was found in the washings of dredged 

 material taken some miles off Peel in June, 1895. This 

 species is known as a messmate within the shell of the 

 " horse mussel " {Mytilus modiolus), and has been recorded 

 by Canu (" Les Copep. du Boulon.," p. 238, pi. xxx., fig. 

 14 — 20), and more recently by Mr. T. Scott from the Firth 

 of Forth. It had also been found previously by Mr. A. 

 Scott in the " Hole " to the east of the Isle of Man. 



The expedition of October 27th in the steamer "Rose 

 Ann" was exceedingly prolific, large numbers of Copepoda 

 being found on the bottom in shallow water (15 to 20 

 fathoms) although there was very little in the surface 

 tow-nets. From some of the dredged stuff (broken shells, 

 &c.) Mr. Scott obtained 35 species three of which, Ameira 

 reflexa, Idya gracilis and Tetragoniceps consimilis, are new 

 to the district, and eight others seem undescribed forms. 

 Mr. Thompson has obtained already, after only a partial 

 examination of the material, 21 species, of which Dyspon- 

 tius brcvifurcatus is new to the British fauna, and a 

 Cijclopicera seems new to science. Other rich hauls still 

 remain to be examined by Mr. Thompson. 



Mr. A. 0. Walker reports the following additions to our 

 lists of the Highee Ceustacea : — 



PODOPHTHALMATA.
