Lep>osphilus, n. g., Hesse, Ann. des Sc. Nat. t. v. p. 277. Body (entire 
animal) fusiform, consisting of ten segments, of Avliich the first four form the 
pereion and are indistinct. Cephalon small, round, having a median eyej 
and beneath it is the oral aperture, which consists of a proboscidiform organ 
furnished with denticulated mandibles, and supported laterally by three 
pairs of prehensile jaw-feet. Antennm very small, rounded at the ex- 
tremity and furnished with cilia. Pleon having the segments retractile, 
last segment terminating in two small appendages. Embryo oval, having- 
three pairs of appendages. Ova agglutinated and forming a large fiat mass 
on the dorsal surface of the pereion. — L. lahrei’^, n. sp., Hesse, 1 . c. p. 278, on 
the Green Wrasse, among the scales of which it secures a retreat. Length 
10-12 mm., breadth 2 mm. The memoir of M. Hesse on this species likewise 
treats of the history of its discovery and its classification among Lerneans. 
Bucolomban jnctus (gen. et sp. nov.), Hesse, Ann. des Sciences Nat. t. v. 
p. 255. Cephalon round, without rostrum. Eyes distant. Antennae long 
and slender. Pereionic segments subequal, except the first, which is nearly 
one-half longer than either of the succeeding. Pleon slightly narrower than 
the pereion, divided into six subequal segments, of which the ultimate is tri- 
angular and pointed at the caudal extremity. Internal ramus of the posterior 
pair of pleopoda truncate (c«rm?ie«^), denticulated, and fringed with long hairs. 
Pereiopoda slender, spinous, and terminated by a feeble claw. Mouth furnished 
with strong denticulated mandibles. Length 6 mm., breadth 3 mm. Taken in 
the mouth of the Baia hatis as well as in the sand on the shores of Brittany. 
— E. ornakis, Hesse, 1. c. p. 25G, taken on the body of Baia marginata. 
This and the two preceding genera M. Hesse, 1. c. p. 255, has tabulated in a 
modified arrangement of Milne-Edwards’s classification of the tribe of the 
erratic Cymothdidicns.
