distally. Each of these processes is about one-third the length and 

 one-fifth the width of the body. 



The first antennae are 3-segmented, the basal segment but little 

 swollen ; the second pair are biramose, the exopod 2-segmented. The 

 second maxilhie are separate to their very tips, which are slightly 

 enlarged and fused; bulla broken off. The maxillipeds are large 

 and much swollen at their base, with a short, stout, and strongly curved 

 claw, which does not reach the level of the mouth tube. Egg strings 

 one-third the diameter of the body and not quite equaling its length ; 

 eggs rather large and not very numerous. Total length of body, 

 4 mm. Greatest diameter, 2 mm. Combined length of cephalothorax 

 and second maxillae, 6 mm. Length of ovisacs, 3.75 mm. 



Remarks. — This species can be recognized by the absence of ventral 

 processes and the presence of short dorsal processes above the egg 

 strings. The only other species with dorsal processes alone is Bra- 

 chiella lophii Milne Edwards (1840, p. 514. pi. 41, fig. 4), in which 

 they are pear-shaped instead of conical in form. 



LERNAEOSOLEA; new genus 



Body cylindrical, bent into the shape of a horseshoe, the "heels" 

 •smoothly rounded, the "toe" passing into a narrow neck curved up- 

 ward and backward and ending in the head. Ovisacs emerging 

 from the sinus behind the base of the neck and extending backward 

 parallel with the sides of the horseshoe. No caudal rami. Two pairs 

 of antennae but no trace of mouth parts or swimming legs. 



Genotype. — Lernaeosolea lycodis, new species. 



LERNAEOSOLEA LYCODIS, new species 

 Plate 32, Figures 190, 191 



A single female, the holotype, U.S.N.M. No. 60501, was obtained 

 from the flesh of a short brovv^n wolf-fish {AnarJiichas lupus) at 

 Albatross Station 2208 off the coast of New Jersey. 



Female. — Description the same as that of the genus. The head 

 is enlarged a little at the top and produced into a median dorsal and 

 two lateral horns on either side. The dorsal horn and the lateral 

 horn nearest on either side are globular knobs; the other two horns 

 are somewhat elongated but end in round knobs and all the horns lie 

 in the same plane at right angles to the axis of the head. The neck is 

 twisted to the right through an angle of 60°, so that its dorsal and 

 ventral surfacejs are turned lateralh". The ovisacs are narrowly 

 cylindrical, parallel with the sides of the body horseshoe, and reach- 

 ing a little beyond the tips of the latter. 



^ Dr. Wilson did not specify the family for this genus and it is placed hfere tentatively. —
