THE FAMILY CERITHIDAE IN THE INDO-PACIFIC 
Part I: The Genera Rhinoclavis, Pseudovertagus and Clavocerithiun 
by Richard S. Houbrick, 1978. 130 pp-,97 pl. (3 in color), $17.50 
take Wasrioon Malacologists, PLO. Box 4208, Greenville, De oe 
19807. Additional pagination for loose-leaf is as that in "Indo- 
Pacific Mollusca." 
- A i nounces that "This is the first in a series of mono- 
SPRL S ceeatuente on Indo-Pacific cerithid genera (Family Cerithi- 
idae; Subfamily Cerithiinae). In the future, I will treat the gen- 
era Gerithium Bruguiere, 1789, and Clypeomorus Jousseaume, 1888." 
(See selected bibliography, pp. 25-28, for aE ee) of his previous 
works on cerithids of the western Atlantic et al. 
In this careful study there are listed 47 fossil and living world- 
wide species and subspecies of which 17 are living, the living spe- 
cies limited to the Indo-Pacific except for Rhinoclavis gemmata 
from the eastern tropical Pacific. The paper is exceptionally well 
illustrated with photographs and charts; the photographs of the 
species under discussion are placed with the pertinent text. Scan- 
ning electron micrographs of the radula are included for each of 
the 17 living species; the operculum is pictured less frequently. 
Fossil records are noted wherever available. 
The three color plates are particularly well arranged and illustrate 
(1) The Genus Rhinoclavis (33 fig., 6 sp.), (2) Variations in size, 
shape, sculpture and color of Rhinoclavis fasciatus (Bruguieére) (17 
fig.), and (3) The Genus Pseudovertagus Vignal (9 fig., 4 sp.). 
Keys are provided for: Subgenera of Rhinoclavis 
Living species of Rhinoclavis s.s. 
Subgenera of Pseudovertagus 
Living species of Pseudovertagus 
Dr. Houbrick explains the new name of Rhinoclavis (Rhinoclavis) 
diadema, proposed for the species formerly known as Rhinoclavis 
(=Cerithium) nitida (Hombron and Jacquinot, 1854)(pp. 64-66, pl. 
33-35), and also the new subgenus Lon icerithium, type species 
Rhinoclavis longicaudata (Adams anddReeve, 1850), as "it is so 
different from Rhinoclavis s.s. or other living and extinct cerith- 
id genera that I believe it and its precursors merit subgeneric 
recognition. ... (It) is one of the most distinctive and uncommon 
members of Indo-Pacific rhinoclavids." (pp. 85-88, pl. 58-61) 
The Florida fossils Cerithium caloosaense Dall 1892 and Cerithium 
dalli Olsson and Petit, T1964 are put into Pseudovertagus (Cerithi- 
oClava). There is also a list of doubtful species of fossils, 
many of which were described from fragments.
