SACCULINIDiE. 
Prof. Lilljoborg, 1. c. pp. 305 & 326, describes Sacculina carcini, Rathke, 
which he found attached to Carcinus tncenas in Bohuslan as well as on 
the coast of Norway. The Rev. A. M. Norman (Trans. Tyneside Nat. Field 
Club, 186.3-4, p. 185) says that it was dredged off Berwick, attached to the 
pleon of Portunus holsatus. 
Clistosaccus is a new genus that the author says has the foi-m of a more or 
less round and completely closed sac ; it was found attached to the pleon of 
Pagurus hei'nhardus : the following is the description : — 
Animal sacciforme, saccuin rotundum vel ovale clausum et leve praebens, 
latere uno (inferiore) in abdomine Paguri immerso, molli et appendicibus 
ramosis (absorbentibus ?) prajdito, ibique pallii tunica extima chitinosa cum 
cute Paguri coalita. Pallio aperto. Corpus parvulum carnosum ovaria interna 
continens, et tabulis oviferis cteciformibus obtectum videmus. — CUstosaccics 
paguri^ sp. n. 
The Rev. A. M. Norman records it (Trans. Tyneside Nat. Field Club, 
1863-4, p. 185) as having been found on Pagurus Icevis. New to Britain. 
Peltogastridas. 
The genus Peltogaster is divided by Prof. Lilljeborg (/. c. p. 316) thus : — 
Organum adfigeudi

J simplex. 
I Apertura cor- 
poris antica 
P. paguri 
magna, marginata . . P. sulcattis, sp. n. 
minima, neque mar- 
ginata P. microstoma. 
To these M. Hesse adds, in his fourth communication On some new or 
rare Crustacea of the coast of France” (Ann. des Sc. Nat. ser. 5. vol. ii. 
p. 281), another new species under the name of Peltogaster tau, which he 
found on Pagurus pubcscens and P. bernhardus. The author describes it as 
being like the letter T, of which the horizontal bar is very long and the up- 
right leg (^‘ jambage”) very short. It appears very near 1}'^ to resemble P. 
sulcatus of Lilljeborg. M. Hesse has also had the opportunit}" of figuring 
the larval stage of this species. 
The Rev. A. M. Norman (Trans. Tyneside Nat. Fi(ild Club, 18()3-4, p. 185) 
states that PeUogastcr paguri (Riithke) is pjimsiiie on llu^ phion of Pagurus
