Clare Island Survey — Arctiscoida. 37 11 



comma. The back, sides, and the basal parts of the legs are papillose. The 

 papillae are scattered irregularly, not arranged in transverse rows, and some 

 are very lai'ge. Some have the appearance of being the product of secretion ; 

 but if so, they are strongly fixed, and do not come off under rough usage. The 

 claws diverge but moderately. 



Habitat. — Among moss from the sea-shore, Clare Island. 



This animal was recorded in 1905 (11) for Scotland as var. verrucosus of 

 M. ornatus Eichters ; but I have since seen reason to doubt the identity with 

 E-ichters' species. The differences are — the larger size, the possession of eyes, 

 the irregularity of the papillae, and the relatively larger claws of different 

 form. 



All the forms of M. ornatus, including verrucosus, occurred in W. Ireland. 

 All were smaller, without eyes, with papillae in regular transverse rows, 

 and very small claws. The claws are partly united, forming little Y's, with 

 the arms unequal. 



Eichters' name has not been adopted for the new species, because it is 

 believed we are dealing with a different animal, and that there is a verrucose 

 variety of M. ornatus. 



Distribution. — Only known in Scotland and Ireland. 



Macrobiotus augusti Murray. 



Although it has a fairly wide range, since it has been noted for the Arctic, 

 Scotland, Ireland, and Australia, M. augusti seems to be rare, or extremely 

 local. In Scotland it occurs in one patch of bog, and not in any of the 

 numerous similar bogs in the same neighbourhood. Similarly, in Ireland, 

 where the whole country seems suitable for it, it only occurred once. 



M. schaudinni Eichters. (Plate III., figs. 16a, 16b.) 



As Eichters gave no figure with his description of this species, it is here 

 figured. It is a fairly large animal, and possesses eyes, three short rods in the 

 pharynx, and claws of the Diphascon-type. There are some differences from 

 Eichters' animal, but they are too slight to justify its separation in the 

 meantime. 



Irish examples have not the rods very obviously increasing in size from 

 first to third, and very often there is no comma. 



Though only recently described from Spitsbergen material, the animal 

 has long been known in Scotland, and has just been recorded for that 

 country (16). It was abundant in some localities in W. Ireland, though it 

 did not appear to be generally distributed.
