HARVEY'S SYRINX. 



Syrinx Harveii. Forbes.

 two-thirds smooth, with the exception of a band of minute bristles near the ex- 

 tremity.

 dredge in the seas of the Antipodes with equal success. 

 I have dedicated the species to its discoverer. It measures 

 two inches and a half in length. The body is quite smooth, 

 except at the two extremities, where it is finely reticulated. 

 The skin is tender and very lax, which makes me suspect 

 that some of the animals described under the name of 

 Sipunculus saccafais (as that mentioned in " Martin's Ma-

 of the nndus, may have belonged to this species. The 

 proboscis is short, in the preserved specimen being only 

 one-seventh the length of the body, and has a circle of 

 bristly papillae surrounding it near its extremity. Beyond
