 Pl. V, fig. 24—26; Pl. VI, fig. 1 — 13. 



Diagli. Corpus carinatuni, integumento reticulato. Caput rostruin gerens. Ociili paivi obliqui ovati. 

 Segmentum septinmm pereii brevissimum, seginentum secundum loDgissimum ; tiegnienta 

 tria ultima segniento quarto fere duplo longiora. Pedes pereii primi paris metai^arpo crasso 

 fere sphasrico. Pedes quarti paris pedibus (juinti paris iiiulto breviores. Pedes quinti et 

 sexti pariura longitudine fere jequales, quam pereion iiiulto longiores. Pedes septimi paris 

 pedibus quarti jjaris uiulto breviores. Segiueiita plei non serrata. Pedes nri elongati. 

 Tehon pedunculo ultinii paris peduni uri diniidio brevius, lingulatuni. 



The bod^ is keeled, the integinnent reticulated. The head is provided with an obtuse rostrum. 

 The ei/es are small, placed obliquely, ovate. The seventh pereioval segment is the shortest, 

 the second the longest; the last three segments are almost twice longer than the fourth. 

 The first pair of pereiopoda have a thick almost globular metacarpus. The fourth pair are 

 much shorter tlian the fifth. The fifth pair are almost as long as the sixth; botli pairs 

 much longer than the pereion. The seventh pair are much shorter than the fourth. The 

 pleonal segments are not serrated. The uropoda are elongated. The telson is half as long 

 as the peduncle of the last pair of uropoda. 



Colour. Hyaline. 



Length. 22 mm. 



Hab. The mouth of Davis Strait. (D. M.).

This species is at once distinguished from the others by the length of the fifth 

 pair of pereiopoda. It is more slender and delicate than the above described species. 



The Jiody is less arched than in Lanceola Sayana, somewhat depressed; the inlegu- 

 ment is very tliin, finely reticulated as in Lanceola serrata. 



The head is more than three times deeper than long, the obtuse rostruin is almost 

 as long as the rest of the head, the lateral anterior margins of the head are dilated on 

 each side into a broad rounded lobe, on which the eyes are placed. The liead with the 

 rostrum is as long as lialf the first pereional segment. 



The eyes are small, placed a little below the base of the first pair of antenna?. 



The first j)air of antennas (Pl. VI, fig. 3 and 4) are almost as long as the head 

 and the first pereional segment together. The first joint of the peduncle is three times 

 longer than the two following together. The first joint of the flagellum is very high, 

 compressed, nearly three times longer than the peduncle; the upper margin is strongly
