Munna limieola-, G. O. Savs, Beretning om en i Sommeren 1865 foretagen zoologisk Reise veel 

 Kysterue af Cliristianias og Chvistiansands Stifter, p. 29. 



Specific Characters. — Body of female somewhat less robust than in the 

 type species, with the anterior division oval in form. Ocular processes very much 

 projecting. Caudal segment rather large, nearly equalling the mesosome in length, 

 and oval pyriform in shape, lateral edges evenly curved, and without any den- 

 ticles, but clothed with scattered bristles, tip without any serrated lamellae. Eyes 

 comparatively smaller than in M. Boecld, and narrowly rounded. Superior antenna? 

 reaching to the middle of the penultimate peduncular joint of the inferior ones, riagel- 

 lum 5-articulate, last articulation, as usual, extremely small. Inferior antenna? twice 

 the length of the body, fiagellum much shorter than the peduncle. Legs greatly 

 increasing in length posteriorly, and far less strongly built than in M. Boecld; 

 1st pair with the carpus but slightly widening distally, and nearly as long as the 

 propodos; last pair considerably exceeding the body in length, and having the 

 carpal joint rather narrow, propodal joint extremely slender, being almost twice 

 as long as the former. Uropoda nearly as in the type species. Colour uniformly 

 pale yellowish grey. Length of adult female 3 mm. 



Remarks. — Though rather nearly allied to M. Boecld, this species may, on 

 a closer examination, be easily distinguished by its less robust body, the smaller 

 eyes, the form of the caudal segment, and the absence on it of lateral denticles 

 and apical serrated lamella;, and finally, by the extremely slender and elongated legs. 



Occurrence. — This species occurs not infrequently both off the south and 

 west coasts of Norway, from the Christiania Fjord, at least to the Lofoten Islands. 

 It is only found in greater depths, ranging from 60 to 300 fathoms, on muddy 

 bottom. Out of Norway, it has not yet been recorded. 



3. Munna Fabrieii, Kroyer. 



(PI. XLV, fig. 2.) 

 Munna Fabrieii, Kroyer, Nat. Tidsskr, Bel. 11, p. 380. 



Specific Characters. — Body rather short and compact, with the anterior divi- 

 sion rounded oval in outline. Ocular processes rather thick, and less prominent 

 than iai M. limieola. Caudal segment oblong oval, but slightly narrowed behind, 

 lateral edges evenly convex, and each armed in front with a single slender den- 

 ticle; apical lamellae distinctly serrated. Eyes rather large, semi-globose. Supe- 

 rior antenna; scarcely reaching to the middle of the penultimate peduncular joint
