VOL. 83 



are recorded in the National Museum as coming from "England" 

 but \vith a question mark. A third and larger specimen of the same 



lot agrees more nearly with 

 multiannularis and is de- 

 scribed above (p. 542) ; it is 

 the only specimen out of a 

 total of 25 examined from 

 the Atlantic coast of Europe 

 the relationship of which is 

 in doubt, whether it belongs 

 to the present species or to 

 multiannularis. 



Total number of speci- 

 mens examined, 8, 84 to 

 113 mm long (tail in one 

 specimen broken and its 

 length unknown but evi- 

 dently falling within the 

 given range of lengths). 

 Since europaeus obviously 

 has been confused with 

 other species, the onl}'- defi- 

 nite locality to which it 

 may be assigned must be 

 based on the material 

 examined, namely. La 

 Rochelle, and its precise 

 geographical distribution 

 still remains to be deter- 

 mined. All the specimens 

 examined had either a fully 

 developed brood pouch or 

 at least a rudiment of one 

 represented by an oval fold 

 of skin or an oval pigment- 

 ed area under the anterior 

 ])art of the tail. It is possi- 

 ble therefore, that in euro- 

 paeus, as in hippocampus, this structure does not definitely indicate 

 the sex (see p. 510).
