S. lanceolata, White, from the same regions of $. America, of which 
there are no specimens from the Aucklands in the Collection of the 
British Museum, differs only in the rami of the caudal appendages, 
which are narrower-lanceolate and acute at the extremity, and in the 
absence of the lateral marginal groove on the thoracic segments. These 
differences may prove to be only sexual. ’

Hobson’s Bay (Coll. Brit. Mus.). 
Specimens from Port Jackson, Australia, are also in the Collection 
of the British Museum. 
The habits of this species are curious. Dana found it in rotten 
wood in cavities bored by Teredo ; and the specimens from Hobson's 
Bay, in the Collection of the British Museum, inhabit similar cavities 
ina piece of sandstone. It is to be noted that these examples are 
much more hairy than those from Australia in the Collection.
