Occurrence. I have found this form not unfrequently in several places 

 off the west coast of Norway, as also in the Trondhjem Fjord; and Mr. Scott 

 also records it from Finmark (as A. sposrica). It generally occurs in depths 

 varying from 3 to 20 fathoms, on a sandy bottom, and is easily observable, even 

 with the naked eye, owing to its dark red colour and peculiar tremulous movements. 



Distribution. British Isles (Brady), Shetland Isles (Norman), Arctic Ocean: 

 off Franz Josefs Land and Novaja Zemlia (Scott), Ceylon (A. Scott). 



42. Tegastes flavidus, G.' 0. Sars, n. sp. 



(PI. LXII, fig. 1). 



Specific Characters. Female. Cephalic segment about as in the preceding 

 species, with no trace of a chitinous stripe across the back. Genital segment 

 with 2 projections below, the anterior one obtuse at the tip and not recurved, 

 the posterior one broadly claw-shaped. Distal part of urosome much more pro- 

 minent than in any of the other species; caudal setse normal. Posterior maxil- 

 lipeds somewhat less strong than in the preceding species, with the hand narrow 

 oblong in form. Last pair of legs with the distal joint not extending to the tip 

 of the inner expansion of the proximal one, the latter only provided with 2 setse 

 in front. Spermatophore-reservoir in male bluntly beaked at the tip. 



Colour light yellowish gray. 



Length of adult female 0.40 mm. 



Remarks. Though nearly allied to T. falcatus, this form may be easily 

 distinguished by the blunt anterior projection of the genital segment, the feebler 

 posterior maxillipeds, and the unusually prominent distal part of the urosome. 

 The last pair of legs and the male spermatophore-reservoir are moreover somewhat 

 different in form. Finally, the colour of the body is rather different in the two species. 



Occurrence. I have only met with this form in 2 localities of the west 

 coast of Norway, viz., at Kalvaag and Eggesbonses. In both places it occurred 

 rather sparsely at a depth of about 3 fathoms, muddy sand.
