CnMSTIANIA VIDENSK.-SKLSK. FORHANDL. 188 3. No. 7. 13 



spines very large and finely denticulated at the inner margin. 

 Inner lamella of the uropods, a little longer than the outer, both 

 rather shorter than the telson. Usual length of adult female 

 15 mm. 



Hah. Widely distributed, and occurring in almost every part 

 of the ocean: North and South Atlantic, Australian sea. North 

 and South Pacific. Mediterranean, Norwegian eoast. 



Rcmarhs. I think this form must he the Euphattsia pel- 

 heida of Dana. although the description and drawings, do not, in 

 every respect, ftilly correspond with my own observations. The E. 

 Miillcri of Dohrn. from the Mediterrannean. is unquestionably iden- 

 tical with this species, and I also regard the single specimen, 

 eollected by me last year. on the Norwegian coast, and described 

 as Thysanopoda bidentata, as belonging to the same species. 



14. Enphausia similis n. sp. 



Jn general shape, rather like the last species. but much larger. 

 Carapax with only a single, small, lateral, denticle. at the middle 

 of the inferior margin; anterior part slightly keeled above; rost- 

 rum rather produced. and very acute. Epimera of the 4th and 5th 

 postabdominal segment small, and inferiorly truncated. or slightly 

 emarginate. Last segment rather elongated; præanal spine. simple. 

 Eyes moderate, pyriform. Antennular peduncle with a very small 

 bifid lappet above. at the end of the basal joint. Antennal scale. 

 scarcely surpassing the 2nd joint of the antennular peduncle, rather 

 broad. ovate, obliquely rounded at the apex, the denticle on the 

 outer edge, obsolete. Telson narrow. and elongated. with rather 

 small, and quite smooth, subapical spines. Uropods shorter than 

 the telson, inner lamella, scarcely surpassing the outer. Length of 

 the largest specimen: 30 mm. 



Hab. South Atlantic, (Stat. 320) from trawl: 1 adult male 

 and two smaller specimens.
