Remarks. This form was described by Th. S.cott in the year 1898 as 

 the type of the present genus. It may easily be recognized by its short, stout 

 form and the abrupt contraction of the posterior division of the body, as also by 

 the stout and densely hirsute anterior antennae. 



Occurrence. I have taken this form rather abundantly in 2 places on the 

 Norwegian coast, viz., at Bukken and in the Lyngdal Fjord, near Farsund. It 

 is a true deep-water form, only occurring in greater depths ranging from 40 to 

 100 fathoms, muddy bottom. 



Distribution. Scottish coast (Scott). 



Gen. 76. Tachidlella, a. 0. Sara, n. 



Generic Characters. Rudy short, sub-depressed, with the anterior division 

 very much broader than the posterior. Rostral projection not defined behind. 

 Genital segment in female imperfectly subdivided. Caudal rami very short, but 

 with the apical setae rather coarse. Anterior antennae short, 8-articulate, and 

 densely clothed with partly ciliated setae. Posterior antennae with the proximal 

 joint distinctly subdivided, outer ramus comparatively small, bi-articulate. Man- 

 dibles, maxillae and anterior maxillipeds of normal structure. Posterior maxillipeds, 

 however, distinguished by the substitution of a short joint carrying 4 subequal 

 spines, for the dactylus. 1st pair of legs somewhat similar to those in Pseudo- 

 tachidius, the inner ramus being much larger than the outer, and distinctly 

 3-articulate. The 3 succeeding pairs of legs powerfully developed, with the rami 

 subequal in size. Last pair of legs with the distal joint well defined, proximal 

 joint forming inside a rather prominent setiferous expansion. 



Remarks. This new genus in some respects combines characters of both 

 the 2 preceding genera. The peculiar structure of the posterior maxillipeds is very 

 characteristic of the genus, recalling that in the genus Bradya among the Ectino- 

 somidoe. I am as yet acquainted with only a single species. 



213. Taehidiella minuta, G. 0. Sars, n. sp. 



(PI. CCXXI). 



Specific Characters. Female. Body comparatively short and stout, with 

 the anterior division regularly oval in form, and sharply marked off from the 

 posterior. Cephalic segment large, exceeding in length the 4 succeeding segments 

 combined; rostral projection rather prominent and narrowly rounded at the tip.
