CARL BOVALLIUS, AMPHIPODA HYPERIIDEA. 



4. LANCEOLA LOVENI, C. BOVALLIUS, 1885. 



'The name in honour of Professor Sven Loven. 

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



Diagll. Corpus carinatum, integumento reticulate Caput rostrum gerens. Oculi parvi obliqui ovati. 

 Segmentum septimum pereii breyissimum, segmentum secundum longissimum; segmenta 

 tria ultima segmento quarto fere duplo longiora. Pedes pereii primi paris metacarpo crasso 

 fere sphasrico. Pedes quarti paris pedibus quinti paris multo breviores. Pedes quinti et 

 sexti parium longitudine fere aequales, quam pereion multo longiores. Pedes septimi paris 

 pedibus quarti paris multo breviores. Segmenta phi non serrata. Pedes uri elongati. 

 Telsou pedunculo ultimi paris pedum uri dimidio brevius, lingulatum. 



The body is keeled, the integument reticulated. The head is provided with an obtuse rostrum. 

 The eyes are small, placed obliquely, ovate. The seventh pcreional 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 than the fifth. The fifth pair are almost as long as the sixth; both 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 body is less arched than in Lanceola Sat/ana, somewhat depressed; the integu- 

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



The head is more than three times deeper than long, the obtuse rostrum 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 head with the 

 rostrum is as long as half the first pereional segment. 



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



The first pair of antennce (PI. 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
