Ampharetidce, held to be much more nearly allied to the Terebellidce , than to 
the Amphictcnidcc , but with no connecting link with either family. The 
family divided into 4 groups, viz. : those with paloo (including the type 
Ampharete and the type Amphicteis), those without paloo (including 
tho type Sabellides ana the typo Sarny tha ), those with numerous body 
segments with Melinna only as type, and those with Auchenoplax as 
type ; Fauvel (3). 
Ampharete grubei , Mgrn., external morphology, distribution, formation of 
tube, internal anatomy and histology; Fauvel (3), pp. 13-132. A. 
vega (Wiren), description and figure; Birula (2), p. 102: A. patago-

another ; Ehlers, Magal. Reise, p. 129.

cteis) invalida ; Birula (1), p. 18.

the genus s. s. in the Caspian; Birula (1), p. 17. A. antiqua , n. sp., 
G. of Taganrog, and Caspian Sea, regarded as a collective sp. or (?) 
as the type of a new genus Hypania ; Ostrooumouff (1), p. 114. Also 
described and its relation to A. invalida dwelt upon by Birula (1). 
(A.) invalida , Gr., referred to genus Hypania , Ostrooum., distri-

Arenicolidce : relation of the family to tho Maldanidce\ suggested fusion 
of tho 2 families to form a new fam. Arcnicolo-maldanidce, to include 
also his own fam. Clymenidce ; M&snil (2), p. 164.
