A study on the true identity of Clavatula martensi von Maltzan, 1883 (Mollusca: Gastropoda: Clavatulidae) resulting in the description of a new species, Clavatula matthiasi, pp. 7-11, plates I-V by Frank Nolf.

The real status of Clavatula caerulea (Weinkauff, 1875) and Clavatula martensi von Maltzan, 1883 is established and differences between the two species are discussed. A new species Clavatula matthiasi from Senegal, showing some similarity with C. martensi, is introduced.

Keywords: GASTROPODA, CLAVATULIDAE, Clavatula caerulea, Clavatula martensi, Clavatula matthiasi, new species.

Two new turrid species from Congo-Brazzaville: Clavatula hattenbergeri and Clavatula congoensis (Mollusca: Gastropoda: Clavatulidae), pp. 17-20, plates I-IX by Frank Nolf & Johan Verstraeten.

Two new turrid species from Congo-Brazzaville are described and figured. The samples were collected in muddy sand at Pointe-Noire in the mouth of the Songolo-river. These animals seem to be endemic for that locality as no other similar shells are recorded from other West African areas.

Keywords: GASTROPODA, CLAVATULIDAE, Clavatula hattenbergeri, Clavatula congoensis, new species, Congo-Brazzaville.
