5. Notocirrus scoticus, M'Intosh, 1869 [see also under par. 7]. On 

 the Structure of the British Nemerteans, and some new British 

 Annelids. Tr. E. Soc, Edinb., XXV., p. 417. Points out that at least 

 three species of Lumbrinereidae had been previously recorded in British 

 seas, viz. Lysidice ninctta (Aud. Edw.), Lunibriconereis tricolor (Mont.), 

 and Lumhriconereis latreillii (Aud. Edw.). " The two latter have prob- 

 ably been confounded with the L. fragilis of Miiller, a species abound- 

 ing on our northern and southern coasts." N. scoticus was taken in 

 6-9 fathoms in Lochmaddy, and subsequently in several parts of the 

 Hebridean Seas. Body moniliform, much slenderer than L. fragilis; 

 head acutely conical, with two eyes ; parapodia ligulate ; setae uniform.

Specimen taken at St. Malo Ih feet long ; Grube saw only two eyes.

 fathoms. 



This is said to be the N. scoticus of M'Intosh [see under par. 5], which 

 Ehlers erroneously identified with Johnston's Lumhrineris tricolor. It 

 is described as having an ovate prostomium with two eye-spots ; body 

 submoniliform ; maxillae I. unequal and without a large terminal claw. 

 The character of the jaws resembles that described and figured by 

 Marion and Bobretzky [Etude des Annelides du Golfe de Marseille. 

 Ann. Sci. nat. (6) II., 1875, p. 15, PI. I. f. 2] for Notocirrus ge^iiculatus, 

 Clpd., and proves conclusively that N. scoticus is quite distinct from 

 our species.

 Mittheilungen iiber die Familie Eunicea. IP*" Abth. Lumbriconereidea

Grube here expresses his well-founded suspicion that the specific 

 name "tricolor," given by Johnston, was due to a clerical error in 

 copying a label in Leach's collection. He adds that both Montagu's 

 and Johnston's descriptions indicate that the worm belongs to the genus 

 Arahella, and is probably A. quadristriata, Gr. 



*9. Notocirrus tricolor (Johnst.), M'Intosh, 1885. Annelida Poly- 

 chaeta. Chall. Rep. XII., p. 236. M'Intosh here refers repeatedly to 

 Johnston's species under the above name in continuation of Ehlers's 

 mistaken identification [see above, par. 7].
