G46 PROCEEDINOS OF THE NATIONAL MUSEUM. vol.47. 



First antennae slender, cylindrical, slightly enlarged at the tips and 

 obscurely segmented; second antennae with a short and stout basal 

 portion made up of two segments, and two conical rami, each appar- 

 ently unsegmented and ending in a short spine, the exopod nearly 

 twice the length of the endopod. Second maxillae stout, strongly 

 flattened dorso-ventrally, and tapering toward the tips, where they 

 are joined to the slender pedicel of the mushroom bulla. The cepha- 

 lothorax being curved forward ventrally, the bases of these second 

 maxillae nearly meet on its dorsal surface, and they extend forward 

 anteriorly in line with the body axis. 



Maxillipeds large and swollen and inserted on the ventral surface of 

 the bases of the second maxillae, some distance behind the mouth 

 tube; they are made up of two stout conical joints and a strongly 

 curved terminal claw. 



Color (preserved material), a yellowish-white, the swellmgs of the 

 oviducts a light brown, the bulla and its pedicel a dark cinnamon 

 brown. 



Total length, including the second maxillae, 38 mm. Length of 

 cephalothorax, 5 mm.; of second maxillae, 10 mm.; of trunk, 32 mm. 



Width of cephalothorax, 5 mm.; of trunk, 12 mm. Tliickness of 

 the trunk, 7 mm. 



{grandis, huge or immense, alluding to the trunk.) 



Remarlcs. — If the immense size of the trunk and the details of the 

 appendages did not make it certain that this was a new species, the 

 meager material at the author's disposal would not warrant its estab- 

 lishment. Neither female possesses egg strings, the trunk of one is 

 badly mutilated, and there are no data as to host or locahty. And 

 yet it will be evident to anyone that the specimens are certainly 

 new and unique in many respects, and accordingly they are put for- 

 ward as a new species, very much the largest of the genus.

Subfamily characters of female. — Cephalothorax about the same 

 length as the second maxillae, bent backward at a right angle with 

 the body axis; trunk plump, with two posterior processes, but with no 

 genital process, abdomen, or anal laminae; trunk unsegmented; max- 

 illipeds minute and degenerate, removed a long distance behind the 

 mouth- tube; second maxillae removed an equal distance behind the 

 maxillipeds, fused throughout their entire length and armed at the 

 tip with a bulla or with dichotomously branched horns, similar to 

 those found in certain of the Lernaeidae; maxillary glands as external 

 swellings on the trunk at the base of the second maxillae. 



Male. — Unknown. 



Remarlcs. — This subfamily just fills out the possibilities in the mat- 

 ter of the arrangement of the second maxillae and maxillipeds with
