Carapace gibbous, anteriorly keeled and toothed. Eostrum about equal 

 to the carapace in lengtVi, not twice as long as the eye, and shorter than the 

 antenna! scale, nearly horizontal, cnltellate, above with five nearly equal- 

 sized teeth, posterior to which are two others on the carapace ; below with 

 four teeth, all anterior to the fifth tooth of the upper margin. Pront margin of 

 carapace with three pairs of spines ; the first large, above the eye ; the second 

 below the eye ; the third small, at the infero-anteal angle. Third abdominal 

 segment somewhat gibbons, but not dorsally produced ; fourth with a small 

 spine on the lateral margin ; fifth with the infero-posteal angle produced into 

 a conspicuous spine. Second gnathopods reaching the end of the antennal 

 scale. First pcreiopods reaching the middle of the last joint of second gnatho- 

 pods ; second pcreiopods Avith seven-jointed wrist, left as long as right, longer 

 than second gnathopods. Telson furnished with nine jjairs of lateral spines, 

 and terminated in thirteen spines, of which the outermost pair but one are 

 the longest, and the nine spines between this pair are subeqiial in length, 

 and ciliated on both margins. Colour pink, beautifully spotted with crimson. 

 Length, exclusive of antennse, rather more than an inch and a half. One 

 specimen dredged in the Minch. 



Dlastylis lamellata, Norman, n. sp. 



Female. — Ccphalothorax very large, deep and wide in the gravid female, 

 vicAved laterally almost subgiobular, with the dorsal margin boldly arched ; 

 viewed dorsallj', remarkably wide, ovate, greatest breadth in the centre. Cara- 

 pace having a sliort, blunt, horizontal rostrum ; sculptured Avith three oblique 

 raised lamella), the liindmost just at the border of the carapace, and continued 

 round the dorsal margin, the two others are equal distances apart, not con- 

 tinued across the back ; on either side of the central dorsal line is a series of 

 what appear in spirit-preserved specimens to be lucid spots; possibly, however, 

 they may be coloured markings in the living animal. The second and third 

 cephalothoracic segments raised into dorsal lamella of corresponding character 

 to those of the carapace ; the anterior dorsal margin, sixth segment, and the 

 posterior margin of the jn-eccding one denticulately serrate. Superior an- 

 tennre having the three joints of the peduncle subeqtial in length, the internal 

 and longer filament shorter than the last joint of the peduncle. The fii'st 

 pcreiopods have the basal joint narrow and much bent, its inferior margin 

 fringed with pltimoso setaj and furnished with a row of spines ; penultimate 

 joint very long and slender, eqitalling in length the three preceding articu- 

 lations and as long as the basal joint ; terminal joint half the length of the 

 penultimate ; palp two-thirds as long as the basal joint, not furnished Avith 

 any spines. Second pcreiopods having the su2)erior margin of the basal joint 

 furnished with spines, the last and the antepenultimate joints subequal, and 

 more than tAvicc as long as the penultimate ; palp reaching beyond the third
