THE VOYAGE OF H.M.S. CHALLENGED. 
two kinds — smootli and crenated in the fissure, while the bifid ventral bristles are all 
smooth. There are about fifty-seven segments. Length, 45 mm. ; breadth, 12 mm. 
Habitat. — Under stones between tide-marks at Sea Point, near Cape Tovm, South 
Africa, November 1873. 
The species seems to be tolerably abundant at the Cape, and it is noteworthy that it, 
was the only one procured by Kinberg and Schmarda in their well- kn own travels. It is 
evident that both refer to the same form, as Prof. Ehlers^ more than susj)ected, and 
consequently Kinberg’s name has the priority. It belongs to the first group of Ehlers, 
viz., those having the sides of the segments furnished with both cirri and branchiae, all 
the latter, moreover, being ramose. Grube describes the same species from St. Paul, in 
his account of the Annelids of the “Novara” Expedition.^ 
The body of Ewphrosyne capensis is proportionally longer, more finely spinose and 
more flattened than that of the British Euphrosyne foliosa. Kinberg observes that the 
caruncle is semiglobose anteriorly — a feature that has not been seen in these examples. 
Schmarda, again, describes and figures seven tentacles (Ftihler) in connection with the 
caruncle, but such apparently is a misapprehension. None sho'wed any trace of the rudi- 
mentary clavate tentacles observed by Ehlers in his Euphrosyne racemosa. In front of 
the puckered opening of the mouth are the two kidney-shaped pads, separated by a deep 
median fissure. These pads are probably of some importance as pivots during the complex 
actions of the buccal apparatus. A typical segment of the body consists of a convex dorsal 
and a flattened ventral arch. The former is bare in the middle line, but has laterally a 
superior division carrying a dense series of bristles and a posterior row of the branchiae, with 
a cirrus at the dorsal margin and another midway between the bristles and the branchiae. 
The latter is the longer and shows a slight constriction in the middle, but neither tapers 
much. The inferior division, again, presents a tuft of bristles, and interiorly and 
posteriorly a cirrus, which is generally more slender at the tip than either of the fore- 
going. All the cirri are shorter and stouter than in Eiphrosyne foliosa. The dorsal row of 
bristles is comparatively short when contrasted with Euphrosyne borealis, and even less 
boldly marked than in Euphrosyne foliosa ; while their apertures in the thick cuticle appear 
as if punched out. Kinberg’s figure is a very fair, though not quite accurate, representation 
of the serrated kind, while Schmarda’s deviates still further from nature. The curve of 
the tip (PI. Ia. fig. l) is less pronounced than in Euphrosyne foliosa, and the disproportion 
between the processes better marked. When viewed antero-posteriorly, the notches on 
the limbs of the fork are observed to be due to transverse grooves. At the dorsal edge 
as well as in the centre of the row many with a smooth fork occur (PL Ia. fig. 2), the long 
process being much attenuated. All the smooth bristles project considerably beyond the
