Proboscidifera rhachiglossa. 
Macdonald gives a condensed account of his observations on 
the dentition of this division of Gastropoda, preferring for them 
the term Orthodonta as being more expressive. Ann. & Mag.

MURICIDiE. 
Prof. Troschel characterizes this family, his Muricea,^^ by 
the median plate of the radula having three large teeth and two 
smaller between them (the lateral plates being provided with a 
single hook). In the genus Muresc, including the subgenera 
Haustellaria, CJdcoreuSj and Phyllonotus, tlie three teeth of the 
median plate are nearly equal, and the lateral angles of this plate 
are not produced. In Muricidea, Ocinebra, and Trophony which 
must be acknowledged as separate genera, the median tooth is 
placed out of the line of the others, and the lateral angles of the 
plate are produced into tooth-like processes. In Ocinebra several 
accessory teeth are to be found outside of the five normal ones. 
Eupleura (Adams) has nearly the same radula as Ocinebra^ 
Chorus xanthostoma (Brod.) in its radula agrees nearly with 
Trophon. Urosalpmx (Stimps.) resembles Ocinebra ; but the 
median tooth is more produced. The author describes and 
figures the radula of the following species : — 
Murex rarispim (Lam.), hrevisphia (Lam.), tribulus (L.), hrandaris (L.), 
cornutus (L.), ramosus (L.), calcitrapa (Lam.), sencyalensis (Gmel.), ocidatus 
(K^GYe^ypomiformis (Martini), and tnmcidus(\-^‘)) Muricideahlainvillei (Payr.), 
Ocinebra erinaceus (L.), alveata (Kien.), corallina (Scacchi), Trophon gever- 
danus (Pall.), craticidatus (Fabr.), clathratus (L.), gmineri {hoy ^\\), Eupleura 
caudata (Say), Chorus xanthostoma (Brod.), and Urosalpinx cinereus (Say).

Murex. The monograph of this genus is continued by Kiister 
in his new edition of Martini and Chemnitz, section 58, species 
nos. 30-113, pp. 37-110, pis. 16-33. It contains a large number 
of good figures ; but as there is no new species in this monograph, 
this notice will be sufficient. 
Murex hrandaris. The variety with three rows of spines, figured by 
Chemnitz, but very rare, has been found by G. v. Frauenfeld at Gibraltar. 
He is inclined to regard it as a distinct species, Rhinacantha trifariosiyinosa 
(Chemn.). Verb, zool.-bot. Gesellsch. 1869, p. 889. [As specimens often 
occur with only one instead of two rows, and the third is often indicated
