Distribution: Indian Ocean sector of the Antarctic, from 55° S to the 

 coastal waters of Antarctica (Davis Sea). Found in catches from depths 

 of 200-500 m and in total catches from depths of 2,000-3,000 m to the 

 surface. 



7. Lanceola serrata Bovallius, 1885 (Fig. 14) 



Bovallius, 1885b: 7, 1887b: 34. —suhmi Stebbing, 1888; 1313. 



Length of sexually mature males 28-34 mm, females 33-34 mm. 



The integument is thin and finely faceted. Pereon somites V-VII, 

 pleon somites, and somite I of the urosoma have well-developed dor- 

 sal denticles, especially large on the pleon somites. The head is small 

 and high with a poorly developed, obtuse, overhanging rostrum that is 

 sometimes absent. The eyes are small, oval, and bulging. 



Antennae I are longer than pereon somite I; the proximal segment of 

 the flagellum is long and narrow, slightly curved. Antennae II are equal 

 (in females) in length to three-four somites of the pereon together. 



The mandibles have a relatively narrow cutting edge (as in L. loveni) 

 and a longer palp, more than 1.5 the length of the mandibular body. 

 Maxillae II are equal in length and width, with relatively broader lobes. 

 The maxillipeds have narrowly oval outer lobes with long setae; the inner 

 lobes have fairly short setae.
