Rev. Canon Norman— A Month on 
the Anomia pubescens of Gmelin is the same thing.” 
If we turn to Gmelin, Linn. Syst. Nat., edit. xiii., 
we find that the name Anomia pubescens is given 
to a shell on which Miiller (Zool. Dan. Prod. 1776, 
no. 3007) thus writes :— Terebratula pubescens 
testa tomentosa, subquadrangulari, longitudinaliter 
striata, tomentum non omnes equaliter vestit, spon- 
giamque parasiticam suspicor ;’’ and Gmelin’s own 
observations are ‘‘testa pilis brevissimis erectis 
distantibus, an forsan a Spongie specie adherente ? 
hirta.” The suggestion of these two old writers 
was the true one, while modern writers like Gould 
and Davidson have mistaken this hispid coating of 
sponge for an epidermis! But it must not be sup- 
posed that the hispid coating is due to one particular 
species of sponge. ‘T'wosuch are described by Bower- 
bank—Microciona levis, Bow. (Brit. Spong. vol. iii. 
pl. xxiii. figs. 7-11), and Halichondria albula, Bow. 
(vol. iii. pl. xlv. figs. 21-24). I have now taken 
three specimens at random procured at Rédberg and 
examined the hispid covering; all looked alike to 
the naked eye, but each shell had on it a sponge 
not only specifically but generically distinct from 
the others, and none of them belonging to either of 
the species found on Terebratulina by Bowerbank*. 
Fischer and Ghlert give the same solution of the 
“ epidermis,” having found an incrusting sponge on 
their specimens which is yet another species, Sub- 
erites capillitium, 'Topsent. It would seem that the 
slightly roughened shell, combined probably with 
the advantage afforded in the way of nutriment 
brought by the currents of water which the Bra- 
chiopods set in motion, serve to make Terebratulina 
a friend highly esteemed among the Spongozea. 
2. Waldheimia septigera, Lovén. 
This fine species is not rare at some spots near Rédberg ; 
but I only myself found one living specimen on the preci- 
pices on the west side of the fiord at a great depth, probably 
300 fathoms. I have also dredged it at a nearly similar 
depth off Batalden, near Floré. The Rédberg specimens 
are, however, larger than any I have seen from other places, 
* One of the three is Myailla ambiqua, Bow. (=Microctona ambigua, 
Bow.). 
This is Hastatus ambiguus, Fristedt, who also found it incrusting 
Terebratulina.
