bearing at the apex a long slender spine having a slightly 



thickened base, and a small hair; a short seta also springs 



from near the base of the upper margin. Mandibles 



elongate narrow, denticulated on the oblique apex, palp 



rudimentary and consisting of a single moderately long 



hair. Maxillae two-lobed, both lobes of about equal 



length, but one is slightly narrower than the other and is 



furnished with one seta at the apex, the broad lobe has 



four setae on its apex. Foot-jaws somewhat similar to 



those of Collocheres gracilicauda (Brady). First four pairs 



of swimming feet also similar to those of that species ; the 



outer branches of all the four pairs are armed with short 



dagger shaped spines and the terminal joint of the inner 



branch of the fourth pair is furnished with one stout 



dagger shaped spine on the apex and a smaller one near the 



middle of the outer margin. Fifth pair of feet somewhat 



rudimentary, two-jointed, basal joint broadly triangular 



in shape, the second joint which is attached to near the 



middle of the outer margin of the basal joint is elongate, 



curved, and bluntly serrated at its apex, the length being 



about equal to three and one-half times the breadth ; it is 



furnished with three setae, one on the apex and two a 



little lower down on the outer margin and slightly 



separated from each other. Abdomen slender, four-jointed, 



genital segment elongate narrow, length nearly equal to 



twice the breadth, and longer than the combined lengths 



of the next three segments, second joint about one-third 



the length of the first, third joint slightly smaller than 



the second, fourth joint smaller than the third. Caudal 



stylets about four times as long as broad and nearly equal 



to the length of the last two segments of the abdomen. 



Habitat, off Port Erin, from dredged material collected 

 June, LsDo, only one specimen has been observed. 



Remarks. — This species is not unlike Golloclieres gracili-
