Two new species of the family Muricidae are described. Chicoreus (Siratus)
colellai, from off Veracruz, eastern Mexico, is compared with C. (S.) artic
ulatus (Reeve, 1845), and differs from this latter species in many aspects.
C. (S.) caudacurta, from off Puerto Rico, is somewhat similar to C. (S.) b
eauii (Fischer & Bernardi 1857), but differs in having a broad, paucispiral
protoconch, a higher spire,and a shorter siphonal canal.
