setae, in this respect bearing a resemblance to ]\Ialmgren's genus 

 Laenilla} 



The dorsal setae are nearly smooth, bnt faint serrations can be 

 observed along the convex border with a high magnification. The 

 greatest peculiarity in the parapodial armature is presented by the 

 ventral setae, which have gaping bifid tips with a small accessory 

 tooth between the larger prongs. The number of paired alternating 

 spinous rows on the ventral setae is about twelve, the eighth row 

 occurring at the point of maximum dilatation. 



Several specimens were obtained off Cape Adare in 20 to 26 fathoms 

 at a temperature of 29° Fahr. In the state of preservation in which 

 they arrived they proved to be excessively fragile, the cirri and elytra 

 breaking off with the greatest ease and even the intersegmental 

 junctions giving way. 



PHYLLODOCEIDAE. 



5. PlIYLLODOCE MADEIRENSIS. 



(PI, XLIL, fig. 5, and PI. XLIV., fi-. 7.) 



Phyllodoce (Anaitis) madeirensis, Langerlifins, P., 18^0. Zeitsrhr. iciss. ZooL, 

 XXXIII., p. 307. Ehlers, E., 1807, op. cit., p. 25. 



Prof. Ehlers pointed out that the Antarctic representative of tlie 

 Madeiran Phyllodoce differs from the original type in the cliaracter 

 of its setae, the terminal spiniform process of which is very much 

 longer than in the latter. 



On account of the serial distribution of papillae on the extruded 

 proboscis, this species should presumably be regarded as a Phyllodoce, 

 s. str., and not as an Anaitis.'^ 



The proboscis has six lateral rows of papillae, ten to twelve in a 

 row, and a median dorsal series of seven. All the papillae are 

 characterised by a patch of chocolate-brown pigment on their posterior 

 faces only (PI. XLIL, fig. 5). 



^ Many of Malmgren's genera have been rejected by subsequent systenmtists, 

 and among others the type species of Laenilla, L. i,lahra, is now named 

 Barmathoe setosissima (8av.), Mcintosh, 1900, p. 345. I do not quite see 

 the necessity for sinking the name l.aenilla in Harmothoe, especially since the 

 type species turns out to be valid (apart, of couise, from synonymy), and, in fact, 

 the distinction between Laenilla and Malrivjrenia is drawn extremely fine, the cirii 

 of Laenilla being sparsely papillose, and the head of a different shape.
