]\Ir. J. AY. Prjde on Annelida Polychceta 



(Ehlers), Madeira {Langerhaus) , and to Norway. In tlie 

 ' Porcupine ' Expedition of 1870 it was dredged in 81 fathoms 

 off Cape Finisterre, but in the same expedition of the pre- 

 ceding year it was dredged in 370 fathoms off Ireland. 



Tlie head, which was present on one fragment only, was 

 bluntly conical, and when viewed laterally was ovoid in out- 

 line. The dorsal process, present in fresh specimens, was 

 missing. The body, which was slender, tapered posteriorly, 

 but unfortunately none of the animals had the caudal region 

 present about the number of cirri, of which there is still some 

 doubt. Ehlers Avorked from incomplete examples, and the 

 Avriter of the Monograph obtained one with this region 

 present, but the cirri were absent. No specimen showed an 

 extruded proboscis which is armed with a dental apparatus 

 consisting of a pair of curved jaws and a pair of great dental 

 plates, each of which bears four strong teeth*. 



Living examples have an iridescent buff colour^ but the 

 preserving fluid has considerably bleached the specimens of 

 this collection. The foot resembles the type-foot, but the 

 hooked bristles bear terminal pieces which are slightly 

 larger. The winged bristles are slightly curved and taper 

 to very fine points. Moreover, the wings on the biistles in 

 the posterior region are somewhat broader than those in the 

 anterior. 



The jNIonograph states that L. coccinea of Renier, Nardo, 

 aud Grube comes near to this species. 



Genus Eunice, Cuvier, 1817. 

 Eunice norvegica, Linnaeus, 1766 {=pennuta, 0. F. M.). 



Most of the examples of this form are small, and have 

 suffered from the fire in the laboratory which was mentioned 

 in the introduction to Part IL The following aie the 

 stations where the annelids were procured : —
