186 MR. LUBBOCK ON SOME OCEANIC ENTOMOSTRACA 



Sapphirina Thompsojs^i, n. s. Maris consi^icilla non coniuncta, fronti insita. Digitus 

 et articulus secunclus antennarum anticarum egedem fere longitudinis, articulis 

 duobus digiti insequis, unguiculo longiusculo (dimidium digiti longitudine supe- 

 rante). Lamellae caudales latse, latitudine tamen longiores, apice interno producto et 

 aciito ; sette caudales quatuor, duse apicales, aliae externee, onines breves (dimidio 

 lamellee breviores). 

 I have named this Sapphirina after Mr. Thompson, thinking it btit right that one 

 species should be dedicated to the discoverer of the genus. The body consists of ten 

 segments gradually tapering backwards,— the posterior, however, being, as usual, small 

 and almost concealed beneath the penultimate. It is of a somewhat peculiar form ; so 

 that I have given a separate figure of it. The first five segments are rounded at the sides, 

 the next four have a minute spine at the posterior corners. The seventh, eighth, and 

 ninth segments have on the under side a small toothed flap. The anterior antennee have 

 only three apparent segments, the first and third about equal, the middle one shorter. 

 The setee are short. The total length is -^^ths of an inch. The width of each conspicillum 

 is Y^to". and the space between them -aoW- The length of the second segment of the pos- 

 terior antenna is af&o", and that of the finger is the same ; the claw is ^t o" ; ^^^ length 

 of the caudal lameUa is ^^o", and their breadth -^H-q. The caudal setse are 2/00" in 

 length. 



Collected February 1, 1S58, at 3 a.m., in S.lat. 0° 30', W.long. 0° 30'.
