Anilocra Hedenborgi, n. sp. 



The name in hononr of Doctor Johan Hedenborg, a zealous coUector 

 of zoological specimens for the R. Swedish State museum. 



Diagn. Corpus fere ellipticum, plus quam duplo longius quam latius. 



Caput magnum, triangulatum, duplo latius quam longius. 

 . OcuU ovati, valde distantes. 



Åntenncc primi paris teretes, non dilatatae. Antennae secundi 

 paris antennis primi paris teretiores ac longiores. 



Epimera segmentorum secundi et tertii segmenta explentia, 

 cetera segmentis multo breviora. 



Pedes j^erm quarti paris ceteris breviores. 



Segmentum primum plei secundo longius. 



Urus fere rotundatum quam pleon vix longius; latius quam 

 longius. 



Uropoda ramis elongatis ovatis, interno breviore. 



The bodij is nearly clliptical, more than twice as long 

 as bro ad. 



The liead is largc triangulär, twice broader than long. 



The eijes are ovate, widcly distant. 



The iirst pair of antenure are slender, not dilated or in- 

 flated. The second pair are longer and more slender than the 

 ilrst pair. 



The epimerals of the tirst and second segments are as long 

 as the segments, the others are much shorter than the corre- 

 sponding segments. 



Tlie fourth pair of pereiopoda are much shorter than the 

 others. 



The iirst segment of the pleon is longer than the second. 



The urus is broader tlian long, nearly rounded, scarcely 

 longer than the pleon. 



The rami of the uropoda are elongate-ovate, the inner 

 ramus is shorter tlian the outer. 



The nearest allies to the animal are Anilocra physodes 

 and A. laticauda, Milne-Edwards. From the first our animal 

 diffcrs by tlie form of the antennas and the epimerals, from 

 the lattcr by the length of the foiirth pair of pereiopoda, the 

 form of the urus, and by tlie short inner ramus of the uropoda. 



Ovi<jerous female. 

 Pl. III, fig. 39. Pl. IV, fig. 40—45. 



The body is tolcrably convex transversally and longitud-
