186 MR. LUBBOCK ON SOME OCEANIC ENTOMOSTRACA 
Sapphirina Thompsoni, n. s. Maris conspicilla non conjuncta, fronti insita. Digitus 
et articulus secundus antennarum anticarum eaedem fere longitudinis, articulis 
duobus digiti insequis, unguiculo longiusculo (dimidium digiti longitudine supe- 
rante) . Lamellae caudales latae, latitudine tamen longiores, apice interno producto et 
acuto ; setae caudales quatuor, duae apicales, alias externae, omnes breves (dimidio 
lamellae breviores). 
I have named tbis Sapphirina after Mr. Thompson, thinking it but 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 antennae have 
only three apparent segments, the first and third about equal, the middle one shorter. 
The setae are short. The total length is - 2 %ths of an inch. The width of each conspicillum 
is ¥io o"» a n<l the space between them 2W00"' The length of the second segment of the pos- 
terior antenna is - 2 -wo"> an( i * na * of the finger is the same ; the claw is -0M0" '•> * ne l en g tn
