the dactylus only armed with 3 serrations at the base; daotylus of the 

 posterior giiathopoda serrated only in its proximal half, the serrations being 

 f) in Hinnl)er. Pereiopoda comparatively less slender than in L. pallida, last 

 pair liaving tlie meral joint ratlier broail and shorter than tlie cnr]!:!! mie, 

 propodal joint setons on the CAiter edge, dactylus aljout half its length and 

 very slender. Last pair of uropoda with the outer ramus quite naked, inner 

 one armed with only a single denticle on the inner edge. Telson having 

 tlie (deft rather wide, and extending nearly to tlie base, terminal lobes con- 

 siderably diverging, and each armed at the bidentate tip with a slender 

 spine. Body whitish, pellucid, with reddish violet, translucent intestine. 

 Lengtli of adult female scarcely exceeding 3 mm. 



Bemarks. — This form, first described by Sp. Bate, was referred })y 

 that author to his genus Phopdra, tliough in all characteristics it is a true 

 LiUjehorgia., and even very nearly allied to L. pallida, from which it is chiefly 

 distingnishalde by its small size, the diiferent armature of the metasome, 

 the small rounded eyes, and the somewhat different shape of the telson. 



Occurrence. — I have only met with this species in 2 localities of the 

 Norwegian coast, viz, at Haugesrrnd and in the Trondhjemsfjord. In lioth 

 localities it occurred very sparingly in a depth of (5 — 10 fathoms, on a bottom 

 (if c(iarse sand. It is now for the first time added to the fauna 

 of Norway. 



Bislrihiiiion. — British Isles (.Sji. Bate), coast of France (Ohevreux). 



•2s Lilljeborgia macronyx, G. o, Sars, n. sp. 

 (in. 188, ng. 2). 



Body considerably more slender than in the la!5t species, with the 2 

 anterior segments of metasome and the 1st segment of urosome each pi'oduced 

 to a single small dentiform projection. Cephalon about the length of the 

 first 2 segments of mesosoine combined, rostral projection well marked, lateral 

 corners sHgthly produced, and obtusely acuminate at the tip. Anterior pairs 

 of coxal plates fully as deep as the corresponding segments, l.st pair somewhat 

 expanded distally ; 4th pair angularly produced below the posterior emargina- 

 tion. Last pair of epimeral plates of metasome produced at the lateral 

 corners to a very small dentiform projection. Eyes inconspicuous in alcoliolic 

 specimens. Superior antennae somewhat exceeding in length '/a of tlie body, 

 and reaidiing considerably beyond the peduncle of the inferior ones, Hagellnm 

 nearly twice the length of the peduncle, and composed of about 12 articulations,
