Rhagidia halophila (Lab.). 



There is referred to this species a rather large Ehagidia, which was found 

 under stones partly embedded in sandy mud, &c, and also running with 

 great speed on rocks, between tide-marks, on the shore at Mulranny in 

 September. 



It was recorded by Moniez in his paper on marine mites and insects 

 under the name of Norneria halophila Lab. His remarks concerning 

 its habits apply excellently to its occurrence on the Irish coast, and 

 are worth repeating : " Xous avons assez souvent trouve sous les fucus 

 ou sur les pierres que recouvre la maree, un Aearien d r un beau rouge que nous 

 avons aussi rencontre hors de la portee des eaux de la mer, sur la falaise, ou 

 meme a l'interieur des terres, dans des stations variees, toujours un pen 

 humides. II est remarquable par son extraordinaire agilite et par les 

 mouvements eircidaires qu'il decrit volontiers ; il est de nature fort delicate 

 et on l'endommage facilement en le voulaut prendre " ( 52 ). 



As the species has not been satisfactorily described the following notes on 

 its structure may prove useful. The Irish specimens (female) measure as much 

 as 12S0yu in length ; breadth 640u. Colour during life, orange. The length of 

 the mandible from its base to the tip of the fixed chela is about 352/u,
