1. Squilla brasiliensis, n. sp. Figs. 1-3. 



Occurrence. — Station 42 (near Cape Frio, Brazil). Bottom fauna, 40 fathoms. 

 Three females (including holotype), four males. 



Description. — Total length (holotype), about 106 mm. Length of carapace 

 (excluding rostrum), 24 mm. 



Dorsal surface between the cariuae 

 faintly rugose and polished. Breadth of 

 carapace behind antero-lateral teeth 

 about one-half of its length. Anterior 

 margin on either side of rostral plate 

 straight and sloping backward, so that 

 the tips of the small antero-lateral 

 teeth fall well behind the level of the 

 frontal edge. Lateral margin angled 

 posteriorly. 



All carinae of cai'apace well 

 marked. Median carina forked in front 

 and behind, the posterior fork hardly 

 visible in front of cervical oroove. 

 Dorsal pit equidistant from frontal 

 margin and cervical groove ; anterior 

 fork of median carina extending not 

 more than halfway from frontal margin 

 to dorsal pit. 



Eostral plate fully as long as it 

 is broad at the base, sides converging 

 to a rounded tip, which just reaches 

 or slightly overlaps the hinder edge 

 of the ocular somite ; median carina 

 indistinct. 



Anterior lobe of ocular somite 

 rounded, with a slight median emargin- 

 ation. Eyes with corneal axis longer by one-fourth than peduncular axis, set 

 oblicjuely. 



Dorsal processes of antennular somite with spiniform points, directed forwards. 

 Antennular peduncle equal to, or slightly longer than, the carapace. 



Third segment of mandibular palp little longer than the second. 



Raptorial limb without a tooth on proximal segment ; carpus with anterior 

 ridge divided into two, rarely three, teeth ; propodus more than three times as long
