The bristles on the posterior portion of the list aredifficult to observe with certainty; they seem to exist in moderate number and not to be arrangedin clear groups. Between tlie list and the posterior margin of the shell no bristles seem to occur,nor is any pocket-like formation observable here. First a n t e n n a (fig. 4): — Of the three bristles on the second joint the posteriorone is the longest, being in most cases about as long as the total length of the third to the fifthor the third to the sixth joints; the lateral one is the shortest, in most cases about as long asthe total length of the tliird and lourth joints. The third joint has two anterior bristles and (me. Fig. LXXVI11. — Ph. (Sderocnncha) Appdloji n. sp. — H. Hoslrum nf Uu- ri^lil valve seen from inside, ?; 82 X.

Of tlie two anterior ones, which are situated somewhat distally of the middleof the joint, the anterior one is often somewhat longer than the other and about as long as thetotal length of the third and fourth joints. The posterior bristle on this joint is in most casesabout as long as the shorter of the two anterior ones. The fourth joint has two anterior and fourposterior bristles.
