shape, rather acuminated posteriorly, slightly narrowed in front. 

 Along the back it is marked with variously shaped reddish marks ; 

 it is striated transversely, the strife distinct, marked with small, 

 flattish, indistinct warts, and more sparingly with elevated brown 

 granules. The caudal extremity is densely and rather strongly gra- 

 nulated, the granules of a reddish-brown colour and elevated. The 

 proboscis at the root, next the bod}', is also densely granulated ; 

 anteriorly it is circularly striated, sparingly granulated, and ringed 

 dorsall}' with reddish brown. The extremity of the proboscis, in 

 the only specimen we possess, is withdrawn, so that the tentacles 

 cannot be seen.

The body of the worm is of a whitish colour, obsoletely trans- 

 versely striated, marked here and there with reddish-brown spots, 

 and covered widi small red granules, which are nearly simihir in size 

 anteriorly and posteriorly. It is more attenuated anteriorly, and 

 sends out a very long proboscis, which is narrow, not tuberculated, 

 but distinctly circularly striated, and fasciated with interrupted broad 

 bands of brown. Posteriorly the body is blunt, but becomes sud- 

 denly pointed at the very extremitJ^ The broad bands of brown on 

 the proboscis, the marks of red on the body, and the small tubercles 

 on the surface are all nearly confined to the dorsal aspect, the abdo- 

 minal region being nearlv white. 



Is this the Sipunculus Icevis, CimQr=^ Phascolosoma Iceve, Kefer- 

 stein? In the 'Zeitsch. f. wiss. Zool.' 1867, p. .tO, Keferstein men- 

 tions having received a specimen 11 mm. long from Fayal, Azores; 

 but in some respects his description differs from that of the species 

 here given.

Corpus fusiforme, breve, titrinque utlemuUum, striis circularibus 

 cinctum, fere lave, parte caudali acuminata, granulis majuscvlis 

 obsita, parte anteriore verrucis complunatis sparsis instructa, 

 parte ewsertili circulariter striata ; tentacuUs absconditis.

The body is fusiform in shape, a little attenuated at both extre- 

 mities, rather more so at the caudal termination, which is somewhat 

 acuminated and covered with raised warty-looking granules. The
