The head measures 044—0*5 mm. across at the widest partof the lips. The latter (fig. 1, D., V.) are large, semicircularin general outline, with an indentation in the anterior margin,and with projecting posterior angles. The dorsal lip (fig. 1, V.)has two fairly conspicuous bilaterally symmetrical papillse(fig. 1, P.). Each ventro-lateral lip has also two papillae,but these are arranged asymmetrically with regard to each Fi<r. Crossophorus collaris.

The latter papilla is verysmall. There is a very distinct constriction behind the lips, occupiedby a collar consisting of an apparently double row of * Not Crossophorus, Brady, 1880 [Crustacean], Voy. * Chal-lenger, Zoology, i. 3, Ostracoda. 346 Mr. H.
