1238 CRUSTACEA. 



tinted, or are quite colourless. The species were not observed to be 

 phosphorescent. 



The genus Sapphirina was established by Thompson,* after a species 

 collected near the Cape of Good Hope. His description is, however 

 imperfect ; only the male was seen, and the peculiar character of the 

 eyes is not mentioned. Templeton has described a species (S. fulgens 

 from the same region), with little additional information respecting 

 the general characters of the Sapphirinee.f This species is mentioned 

 by Milne Edwards to have been found by M. Raynaud in the At- 

 lantic. Tilesius had described a species previously under the name of 

 Oniscus fulgens.% It is impossible to identify these species without 

 fuller descriptions or better figures. 



In Meyen's Zoological Observations on a voyage of circumnaviga- 

 tion^ there is a species of Crustacea figured (pi. xxvii.), which appears 

 to be a male Sapphirina. The figure is drawn much enlarged, and 

 combines observations of minute accuracy with others of doubtful 

 character. The species may belong to a different genus; yet, the 

 obvious errors are so great, that we suspect the species will prove on 

 further examination to be a true Sapphirina. The conspicilla on the 

 front (having the same position as in our species) are described as 

 concavities or dimples (Griibchen) ; the minute ovoid spot between 

 the lenses within, which are certainly wholly internal, and probably a 

 pair of eyes, is called the mouth (Mund) ; the ovoidal glands at the 

 lower extremity of the genital system, are considered the phospho- 

 rescing organs (Leuchtorgcme) ; and the nervous ganglion, as made out 

 in the figures, is probably the pair of male genital glands. A series 

 of spreading setae radiate from where the mouth is situated; and these 

 differ so widely from any organs in the Sapphirinse, that we might 

 suppose the animal of a different family, were it not for the evi- 

 dent errors pointed out ; and moreover, as these organs are wholly 

 abnormal in character, we suspect that they are merely the setae 

 of the anterior antennas, seen in an upper view, the organs them- 

 selves being concealed under the margin of the cephalic segment.
