REPORT ON THE ( I KItl I'KDIA. 8S 



inferior portion; the upper margin is straight. The umbo projects slightly over the carina. 

 The two carinal margins touch one another over a Long distance beneath the carina. 



Length of the capitulum, 7 mm. 



Peduncle short, conical. Scales large, calcareous ; the edges very prominent. The] 



are not numerous, and arc placed in horizontal rows; vertically no distinct rows can be 

 made out. 



I opened one of the specimens, but the animal had been destroyed. 1 opened a 

 second; it had the animal still within it, but its condition was very poor. So I am 

 able to give only the following information. 



The labrum is bullate ; its free edge is furnished with a row of small but distinct and 

 pointed teeth ; the palpi are not very elongate, rather robust, furnished with hairs not 

 only at the extremity but also at the sides. The mandibles have three teeth and a very 

 short inferior angle, which is strongly pectinated. The maxilke have the edge nearly 

 straight ; only a trace of a notch behind the very broad upper spines. The outer nuixil/a 

 have the bristles not divided into separate tufts. The so-called olfactory orifices are not 

 placed on highly protuberant excrescences. 



The first pair of cirri has unequal branches. The most anterior one is shorter and 

 very thick, the posterior one is much more elongate ; the latter has seven, the former five 

 segments. A distinct interval separates the first cirrus from the five posterior pairs, 

 which are much more elongate. 



The caudal appendages are uniarticulate. 



I found in one of the specimens a small complemental male attached to the interior 

 surface of each scutum near its occludent margin. They were not in a condition fit for 

 investigation. 



This species was taken at two Stations, which, however, are close to one another : — 

 Station 14G, December 29, 1873 ; lat. 46° 46' S., long. 45° 31' E.; depth, 1375 fathoms: 

 bottom temperature, l° - 5 C; bottom, Globigerina ooze. One specimen. Station 147. 

 December 30, 1873; lat. 40° 16' S., long. 48° 27' E.; depth, 1600 fathoms; bottom 

 temperature, 0°"8 C; bottom, Globigerina ooze. Three specimens. 



Scalpellum parallelogramma, n. sp. (PI. III. figs. 15, 16, and PI. IX. figs. 1-5). 



Surface of the valves covered by yellowish, chitinous membrane. Valves fourteen. 

 Carina simply bowed, massive, with the umbo at the apex ; the flat roof is bordered on 

 each side by a distinct ridge, the flat sides are at right angles with the roof, which con- 

 siderably increases in width from the upper to the lower end. Upper latera quadrant- 

 shaped, with the arched sidenotched. Rostrum wine-glass shaped. Peduncle very short. 

 Males three.
