162 Prof. M'Intosh's Notes from the 



The feet at the anterior end of the fi'agment present 

 dorsally a few very long and finely tapered capillary bristles 

 and a series of broad flattened bristles, curved and faintly 

 striated and with tapered extremities. They represent the 

 intermediate forms ushering in the anterior crotchets of 

 C setosa. The ventral division consists of a few shorter 

 capillary bristles and a shorter series of the same curved, 

 flattened, faintly striated bristles, with tapering tips as in the 

 dorsal division. In front of the reproduced tail the dorsal 

 division has a few long, tapering, capillary bristles, the main 

 series, however, consisting of long, stiff, curved, and striated 

 forms, with a nearly cylindrical shaft inserted in the tissues, 

 a constriction being evident before passing through the skin, 

 after which it curves forward, and ends in the long, flattened, 

 curved, and tapering tip. The ventral division, again, has 

 shorter bristles of the same kind as the foregoing, besides a 

 series of stouter crotchets, which have flattened shafts in- 

 serted in the tissues and sliglitly narrowed curved tips 

 tapering to a blunt point. 



This form, therefore, appears to pertain to De St. Joseph's 

 second series, viz., those with capillary bristles in the dorsal 

 throughout and crotchets in a certain number of the ventral 

 divisions of the feet, but the absence of reliable figures 

 makes its relationship to known forms uncertain. 



4. On the Cirratulidse dredged by H.M.S. ' Po'cupine' 

 in 1869 and 1870. 



A Cirratulid {Ch'ratalus tessellatus) dredged in the ' Por- 

 cupine^ Expedition of 1870 at Station 50, off the Algerine 

 coast in 7-51 fathoms, appears to difter from any described. 

 It was probably procured by the tangles attached to the 

 dredge. The head forms a short cone with a large lateral 

 eye on each side just in front of the posterior constriction 

 and the collar of the next segment, which, however, is 

 connected dorsally with the head by a bridge. The mouth 

 0])ens ventrally as a comparatively small apertui'e in the 

 snout in front of the collar. The body is about 2 inches in 

 length and fusiform in outline, the greatest diameter occur- 

 ring at the anterior third, from which it tapers to the snout 

 and more gently to the tail. It is rounded dorsally, flattened 

 ventrally, though posteriorly it is somewhat compressed on 

 both surfaces. The segments are narrow and numerous. 

 Anteriorly the rings are slightly tessellated, after the manner 

 of Scelibrepna, though to a less extent, and this condition 

 probably occurs throughout in the fresh or well-preserved
