 31, pt. 64, 1913, p. 87, pi. 6, fig. 11. 



Description. — " Test free, consisting of a compressed oval cham- 

 ber, furnished with a long neck, at the extremity of which is a 

 phialine rim produced sideways into two short recurved hooks. The 

 base of the chamber is furnished with two solid spines curving in- 

 ward like the pincers of an earwig, from which we have named the 

 species. 



" Total length, including neck and basal spines, 0.24 mm. ; basal 

 spines, 0.05 mm. in length; chamber, 0.12 mm. long, 0.08 mm. broad; 

 neck, 0.07 mm. long ; breadth across apical hooks, 0.08 mm. ; maxi- 

 mum breadth of shell across basal spines, 0.09 mm. 



"A single specimen of this extraordinary little form from Station 

 13. Broken individuals have been observed at one or two GoJd- 

 seeher stations in the Moray Firth. 



" Our species may be compared with that figured by Mr. Millett 

 in 1901 (Journ. Roy. Micr. Soc, pi. 8, fig. 21) described as 'Z. 

 marginata (Walker and Boys) var., very rare.' It agrees with Mr. 

 Millett's specimens in the long neck with recurved spines at the oral 

 extremity, but differs in the shape of the chamber, which is a com- 

 pressed oval, whereas Mr. Millett's specimen was a marginate form, 

 and also in the presence of the strongly curved aboral spines. These 

 are entirely wanting in the Malay form, the aboral extremity of 

 which terminated in a short, blunt process, outgrowing from the 

 carina. 



" The relationships of our species are evidently much closer to L. 

 laevigata than to L. marginata., to which Mr. Millett referred his' 

 specimens. The presence of the long neck with recurved oral spines, 

 common to both forms, is, however, very noticeable." 



The above seems to be the only reference for this peculiar species.
