18 G-. O. SARS. PRELIMINARY NOTICES ON THE SCHIZOPODA. 



Eyes small, although somewhat expanded at the tip. Antennular 

 peduncle almost exactly as in the last species. Antennal scale 

 somewhat more elongated, distinctly surpassing the 2nd joint of the 

 antennular peduncle, obovate. apex rounded, without any denticle 

 on the outer edge. Telson much narrovved in the posterior part, 

 subapical spines rather small and smooth. Inner lamella of the 

 uropods only very slightly surpassing the outer, and not reaching 

 the tip of the telson. Length: 15 mm. 



Hah. North Atlantic and tropical Pacific, surface. 



22. Euphausia spinifera n. sp. 



Form of body somewhat robust. Carapax with a strong lateral 

 denticle, placed in a sinus above the inferior margin a little back 

 of the middle, anterior part distinctly crested above. the crest 

 forming in the middle an erect denticle; rostrum unusualy produced, 

 straight, acute, reaching almost the tip of the basal joint of the 

 antennulæ; a sharp ly pointed tooth on each side of the rostrum 

 above the eyes. Postabdominal segments with rather deepepimera; 

 2nd and 3th segment armed with a posteriorly directed spine above 

 in the middle of the posterior margin, the anterior small, the 

 posterior very strong and mucroniform. 4th and 5th segment with 

 the posterior margin divided in several sharply pointed lappets. 

 Last segment somewhat elongated; præanal spine small, bidentate. 

 Eyes short and thick, almost globular. Antennular peduncle of 

 moderate size, with a rather large bind and anteriorly directed 

 lobe above at the end of the basal joint, and another siinply pointed 

 at the end of the 2nd joint. Antennal scale considerably surpassing 

 the 2nd joint of the antennular peduncle, oblong, obliquely truncated 

 at the apex, outer edge produced in a distinct tooth. Telson rather 

 elongated, the subapical spines narrow and serrate at the inner 

 margin. Uropods reaching the tip of the telson, inner lamella 

 scarcely surpassing the outer. Length: 26 mm. 



Hab. Australian sea and South Pacific, surface. A few speci- 

 mens.
