Laoplionte serrata, Glaus. (PL XX, fig. 6.) 

 Length 1.0 mm. Taken in townet by electric light at 

 Port Erin, also between the Isle of Man and Liverpool 

 and off Puffin Island, but rare. 



Laoplionte spinosa, n. sp. (PI. XXXIII, figs. 1 — 13.) 

 Length 1 mm. Body elongated, the first segment being 

 about equal in length to the five following segments. 

 Kostrum short and blunt. Anterior antennae (figs. 2, 3) 

 four jointed, and with marked differences bearing a general 

 similarity in both sexes to those of Laoplionte serrata and 

 even more serrated than in the latter species. The second 

 joint has a large, strong spine in both sexes. The third 

 joint in the female is longer than the others and is less 

 setose than that of L. serrata. Fourth joint of male very 

 similar to that of L. serrata, the others being dissimilar. 

 Posterior antenme (fig. 4) very similar to L. serrata. 

 Mandible (fig. 5) bluntly spinous with small setiferous 

 palp. Posterior foot jaw (fig. 7) is slender with very long 

 slender claw. 



The peduncle of first pair of feet (fig. 8) is composed of 

 two long slender joints, the outer branch two jointed and 

 very slender springing from the middle of second peduncle 

 joint and about half the length of the first joint of inner 

 branch which is armed with a strong falciform terminal 

 claw. The two jointed outer branch of second, third and 

 fourth feet (figs. 9, 10) in the female is nearly as long as 

 the three jointed inner branch. 



The fifth pair of feet in the female (fig. 12) have large 

 triangular basal joints with three curved lines of fine 

 markings on the surface ; they have five plumose setae, 

 The second joint is ovate and is attached laterally to first 

 joint and also has five plumose spinous setae. The fifth 

 feet of the male (fig. 11) are very small and two jointed. 

 The caudal segments (fig. 13) are about four times as lonoj
