Although I am otherwise leaving the family Serpulacea unmentioned, 

 I will just note that belonging to the tribe Amphicoridee I found not only 

 several specimens ofFahricIa, but also two oiHaplohranchus (A. G. Bourne), 

 hitherto only known to occur at the mouth of the Thames. These were 

 found in tide-pools not far from the mouth of the Tealm. 



With regard to the second object of my visit to Plymouth, namely, 

 to find out how great or how little is the range of variation in homo- 

 logous parapodia, I collected whilst there a large number of specimens 

 of the only Polychset obtainable in any great abundance, namely, Nereis 

 diversicolor, and have begun making camera drawings of parapodia of 

 certain segments in each specimen.
