The body is nearly three times as long as broad. 
The head is large, twice as broad as long. 
The eyes are large, granular, with very large ocelli. 
The first pair of antenne are longer than the head, the 
flagellum four-jointed; the first article of the flagellum is 
shorter than the last of the peduncle. 
The second pair of antenne reach to the anterior margin 
of the sixth pereional segment; the flagellum consists of 
fourteen articles. 
The fifth segment of the pereion is as long as the two 
first together. The three first pairs of pereiopoda are short, 
their metacarpi are armed with a knife-shaped spine. The four 
last pairs are long, the seventh pair however are much shorter 
than the preceding. 
The epimerals are distinct. 
The segments of the pleon are subequal in length. The 
first is totally free not obtected. 
The urus is semicircular. 
The genus Slabberina was founded 1861 by P. J. VAN 
BENEDEN!), some years later SPENCE BATE and WESTWOOD”) 
pretended the new genus to be indentical with the genus Eury- 
dice of LEAcH, an opinion, which I must contradict, since the 
characteristics quoted by LEAcH ”), »Oculi non granulati, an- 
tenne inferiores corporis longitudine», does not agree with the 
animal in question. The specimen described here has »oculi 
granulati> just as an Aega or a Rocinela. VAN BENEDEN states 
1. c. pag 91 that the eyes are granular, which also is easily to be 
seen on the accompanying figure l. c. pl. 15 fig. 3. The British 
authors on the other hand declare expressively, after a very 
careful examination of their type, that »the eyes under a 
strong lens are not faceted>, 1. c. p. 308. Thus the both
