corners less acutely produced than in the 2 preceding species. Ventral protuber- 

 ance of genital segment narrowly produced, with the tip slightly bilobed and the 

 posterior edge projecting in a blunt tooth. Distal part of urosome only slightly 

 projecting, caudal setae normal. Posterior maxillipeds rather strong, with the hand 

 oval triangular in form, palmar edge angularly curved above the middle. Last 

 pair of legs resembling those in T. flavidus; inner expansion of proximal joint, 

 however, with 3 setae along the anterior edge. 



Body of a pale yellow colour, and minutely speckled with reddish brown. 



Length of adult female 0.33 mm. 



Remarks. It is with considerable hesitation that I refer this form to 

 Claus's species. Both the description of this species and the 2 figures given by 

 that author are rather poor, and scarcely suffice for an exact determination; yet 

 the form of the posterior maxillipeds, as represented by Glaus in fig. 14, exhibit 

 at any rate some resemblance to that in the present species. The characteristic form 

 of the ventral protuberance of the genital segment at once distinguishes this 

 species from any of the others here described; but unfortunately this part has 

 been wholly omitted in Claus's figure of the animal (fig. 13). 



Occurrence. Some few specimens of this form were taken, together with 

 T. flavidus, at Eggesbonses, west coast of Norway. 



Distribution. Heligoland (Glaus), British Isles (Brady).

(PI. XLII, fig. 3). 



Specific Characters. Female. Cephalic segment, as in T. longimanus, 

 provided with a distinct chitinous stripe across the back, postero-lateral corners 

 obtusely acuminate. Ventral protuberance of genital segment terminating in 2 

 unequal projections, the anterior obtuse, the posterior tooth-like and extending 

 behind. Distal part of urosome scarcely projecting. Posterior maxillipeds exceed- 

 ingly powerfully developed, hand very broad, with the palmar edge much curved 

 in the middle, and deeply concave below, dactylus strong and curved. Last pair 

 of legs with the distal joint rather short, extending little beyond the middle of 

 the inner expansion of the proximal one. 



Colour not yet stated. 



Length of adult female 0.42 mm. 



Remarks. This forms seems to be most nearly related to T. longimanus 

 Glaus, but is of considerably larger size, and has the posterior maxillipeds much
