156 Miscellaneous. 



indivisis, utrinque mamillis pedalibus seu toris et superioribus et in- 

 ferioribus sine setarum uncinatamm ornatis. BranchisD nullee. 

 Species unica : Notomastns latericeus. 



This species resembles an Arenicolay and belongs, like it, to the 

 family Telethusa. Its nearest ally is Dasybranchiis of Grube (Fam. 

 der Anneliden). Its colour is a brilliant red on the anterior part of 

 the body, brick-red on the posterior, passing gradually into reddish- 

 yellow and yellow. The pedal tubercles are all of a paler red or 

 yellowish-red. Its length is 5-6 inches, and its breadth about 

 ^th of an inch. 



This Annelide is rare, and is found buried in the sand. At Floroen 

 in the Sondfjord it occurs in the Laminarian zone, so that when the 

 reflux of the tide is very great, it may sometimes be obtained by 

 digging. It was also taken at Manger, near Bergen, at a depth of 

 50-60 fathoms, and at Oxfjord, in Finmark, at 20-30 fathoms. 



Clymene Mulleri, Sars, n. s. 



Corpora segmentis 25-27, quorum 17-19 setigeris, 5 ante-analibus 

 nudis ; segmento anali margine cirris 1 5-23 vel pluribus, quorum 2 

 ventrales cseteris duplo longiores sunt, ornato ; lobo capitali declivi, 

 ovato, piano, margine circumdato integro ; segmentis 4 anterioribus 

 setigeris modo aculeum in mamilla pedali ventrali gerentibus. 



This species is usually found of about 4 inches in length and 

 i-^th of an inch in thickness, but imperfect specimens ^th of an 

 inch thick have been met with, and these were probably of larger 

 size. Its colour is yellowish or brownish-red, or flesh- colour ; there 

 is usually a darker ring across each segment at the point where the 

 bristles are placed. It is the commonest species of the genus on the 

 west coast of Norway, where it is found at a depth of 12-50 fathoms. 

 It lives in a cylindrical tube, open at both ends, composed of sand, 

 fragments of shells, &c., like that of Terebella. It approaches nearest 

 to Clymene Ebiensis, Aud. and M.-Edw. 



Clymene quadrilobata, Sars, n. s. 



Corpore segmentis 26, quorum 1 9 setigeris, 5 ante-analibus nudis ; 

 segmento anali margine cirris 35, quorum uno ventrali cseteris 

 longiore ; lobo capitali declivi, ovato, piano, margine cristis duabus 

 lateralibus cutaceis bilobatis circumdato ; segmentis 3 anterioribus 

 letigeris modo aculeum in mamilla pedali ventrali gerentibus. 



Perfect specimens, of which only two have been met with, are 

 about 5 inches long and j^th of an inch broad ; the segments be- 

 hind the middle of the body are of remarkable length. It is found 

 rarely at Floroen and Manger at a depth of 20-40 fathoms. 



Sabellides borealis, Sars, n. s.
