4. VIBILIA MACR0P1S, C. BOVALLIUS, 1887. 



PI. VIII, fig. 1 — 8. 



Diagn. Caput rostratum, segmentis duobus primis pereii longius. Oculi grandes, circulares. Flagel- 

 lum ante nnar urn primi paris lanceolatum, acutum, capite brevius. Pedes pereii curti, robusti, 

 non hirsuti. Carpus pedum secundi paris leviter productus. Tibiae pedum tertii ac quarti 

 parium latae, non tumidae, dactyli longi. Pedes quinti et sexti parium pedibus tertii et 

 quarti parium paullo longiores, femora lata, truncate ovata, dactyli modici. Segmentum 

 secundum et tertium uri coalita. Anguli postici segmenti ultimi non producti. Pedunculi 

 pedum uri primi et secundi parium ramis breviores, pedunculus pedum tertii paris ramis 

 longior. Telson parvum semicirculare, dimidio pedunculi ultimi paris pedum uri multo 

 brevius. 



The head is rostrate, longer than the first two pereional segments. The eyes are large, cir- 

 cular. The flagellum of the first pair of antennce is lanceolate, acute, shorter than the head. 

 The pereiopoda are short, robust, not hirsute. The second pair with very short carpal pro- 

 cess. The tibiae of the third and fourth pairs are broad but not tumid, the dactyli are 

 long. The fifth and sixth pairs are a little longer than the third and fourth; the femora 

 are broad, truncate-ovate; the dactyli are middle-sized. The second and third ural segments 

 are coalesced. The posterior corners of the last segment are not produced. The peduncles 

 of the first and second pairs of uropoda are shorter than the rami, that of the third pair 

 longer than the corresponding rami. The telson is small, semicircular, much shorter than 

 half the peduncle of the last pair of uropoda. 



Colour. White with small red spots. 



Length. 6 mm. 



Hab. The South Atlantic at Lat. 43° 30' S. and Long. 9° 50' V., taken by Captain George von 

 Scheele. (S. M.; U. M.)

This species is very interesting because through the high development of its eyes 

 it connects the Vibilidce with the Cyllopodidte; in all other respects it is a true Vibilia, 

 though perhaps also the rami of the first two pairs of uropoda may bear some resem- 

 blance to those organs in the Cyllopodidce. 



The head is almost as long as deep, the rostrum is very short, shorter than a fifth 

 of the length of the head. 



The eyes occupy almost the whole of the sides of the head; they consist each of a 

 little more than 300 ocelli. 



The first pair of antennce (PI. VIII, fig. 2) are provided with a very stout peduncle, 

 the basal joint is longer than the two following together. The flagellum tapers evenly 

 towards the apex, the first joint is not twice as long as the peduncle (10:7), with some 

 few, very short spines along the upper margin. The terminal joints, two in number, are 

 comparatively large, provided with a few minute hairs,
