Remarks. The forms belonging to this family exhibit several apparently 

 very anomalous characters, especially as regards the general form of the body, 

 the structure of the 1st pair of legs, and the composition of the genital apparatus. 

 Yet in the structure of the greater number of the appendages, they seem to come 

 nearest to the Peltidiidce, in spite of the very dissimilar external appearance of 

 the body. Two nearly-related genera of this family are represented in the Nor- 

 wegian fauna; and I regard the form recorded by Glaus under the name of Amy- 

 mone harpactoides as the type of a 3rd genus. 



Gen. 18. TegaStSS, Norman, 1903. 



Syn : Amymone, Glaus (not Miiller). 



Generic Characters. Body, seen laterally, almost circular in outline, with 

 the back much curved, and the genital segment greatly produced below. Outer 

 segments of urosome generally very short and retractile. Anterior antennae 8- 

 articulate, with the first 2 joints considerably larger than the others. Posterior 

 antennae rather slender, with the terminal joint not dilated distally, one of the 

 apical spines very strong and prolonged; outer ramus biarticulate, with the last 

 joint extremely minute. Mandibular palp uniramous, biarticulate. Maxillae with 

 the palp elongated, biarticulate, exopodal and epipodal appendages wanting. An- 

 terior maxillipeds with the outermost lateral lobe considerably dilated at the end 

 and carrying 3 thickish setae, terminal joint scarcely produced at the tip. Poste- 

 rior maxillipeds with the basal part uni articulate, hand of different form in the 

 different species. First pair of legs with the rami scarcely longer than the 2nd 

 basal joint, the outer one considerably narrower than the inner. Natatory legs 

 with both rami distinctly 3-articulate. Last pair of legs of moderate size, inner 

 expansion of proximal joint in female triangular, distal joint very narrow and not 

 extending beyond the proximal, with 2 slender setae at the tip. No true ovisac 

 present in female, only a single ovum being received between the lamellae of the 

 last pair of legs. The ovoid spermatophore in male contained in a large cornet- 

 shaped reservoir issuing from the genital segment in front, and terminating in a 

 two-lipped, beak-like extremity. 



Remarks. This genus was established in the year 1863 by Glaus, to include 

 some very peculiar Copepoda, some of which he found off Heligoland, and others 

 in the Mediterranean. As however the generic name Amymone proposed by him
