146 " ENDEAVOUR " SCIENTIFIC RESULTS. 



The above synonymy has been taken from St. Joseph's- 

 useful work in which the European Polychsetes are reviewed 

 and the references gathered together. 



I have changed the name of the family, which has hitherto 

 borne the title Ammocharidee since the time when the genus^ 

 was termed Ammochares, Grube ; but as modern zoologists 

 agree in resurrecting delle Chiaje's generic name, the name of 

 the family according to the rules of zoological nomenclature 

 must be derived from its type genus. 



Loc. — Eleven miles S. 74° E. of Cape Martin, South 

 Australia, 21 fathoms. 



Distribution. — From Greenland and Davis Strait to the 

 Mediterranean ; ChiH ; Phihppines ; Japan ; and New 

 Zealand. 



Family TEREBELLID.E. 

 Genus Scione, Malmgren. 



SCIONE HARRISSONI,2 Sp. UOV. 



(Plate xlvii., figs. 26-31.) 



A single individual in its tube of small shells and shelly 

 fragments, Polyzoa and mud so loosely held together that it 

 falls to pieces when the worm is removed. 



The worm measures 34 mm. in length, with an anterior 

 diameter of 3 mm., which posteriorly decreases to I mm. It 

 is ill-preserved, soft and readily ruptured. There are 43 

 distinct segments, but the mid-body is so soft, being partially 

 decayed, that it is not easy to be sure of the number of 

 segments here. The hinder segments, however, are well 

 preserved, and the last 25 carry rather high chsetigerous 

 papillae. The colour is a dull brown, but the dorsal surface 

 of the branchial segment is deep reddish brown. 



It is a female filled with eggs. 



There are 15 notopodial bundles of capilliform chsetae, each 

 bundle inserted in a small prominence. The first bundle is 

 in the 4th segment.

2. So named after the kite Mr. C. T. Harrisson, Federal Covernment 

 Biologist, on board the ill-fated " Endeavour," to whose care we owe the 

 excellent preservation of these Polycha?tes. •
