** Conus aulicus chasing Cypraea talpa in New Caledonia - Published : Oct 19, 2005

This march 17th 2005, while night scuba outside the reef, around 12m of water, Patrick DELESTE (a non-collector friend) and I have seen a rare thing in the natural habitat : a cone shell (Conus aulicus) attacking its prey (Cypraea talpa). First, what a surprise when my light spots this nice species crawling along a rocky slope head down. I immediately identify the specimen to be a Conus aulicus (very uncommon species there) ! It's not a giant but what a beauty ! He crawles fastly like if it was attracted by something... 30 to 40 cm under it, a juvenile Cypraea talpa is hidden in a crevice.

** Lambis robusta Swainson, 1821 A Polynesian Endemic species - Published : May 17, 2005

French Polynesia offers some endemic species to collectors, but they are mainly concentrated in the Marquesas Islands. However, some endemics are not restricted to these Islands. This is the case of our very nice Lambis robusta, Swainson, 1821. This species is found usually outside the reef on the external slope. The average deaph of its habitat may vary from 10 to 25 meters. It is usually found among dead coral fragments and can be difficult to spot. When the shell is cleaned (which may take sometime), a real beauty appears with overall dorsum color is pink to light orange-brown. The "fingers" are dark brown to black colored. The mouth is a mix of black orange and white colors. This species remains uncommon and one must pay a lot of attention to spot this wonderful species. Here are pictures or four specimens I collected at Moorea Island.

** A review of the Bistolida-complex of Africa's north-eastern, eastern and southern coastlines and the adjacent Indian Ocean islands - Published : May 11, 2005

This study document reviews the Bistolida-complex with specific reference to the sp. and ssp. along the north-eastern, eastern and southern coastlines of Africa and the adjacent islands. Some three decades ago in 1977, C.M. Burgess (1977) questioned the validity of some Bistolida sp. on the grounds of conchological similarities or apparent integrades (such as hirundo and owenii; brevidentata and stolida; erythraeensis and stolida; hirundo and neglecta). Much water has flowed under the bridge since then. One of the Bistolida sp. has since been split: stolida diauges gave rise to the sp. diauges and the ssp. stolida clavicola. Two new Bistolida ssp. were described: stolida brianoi and stolida uvongoensis.

** Conus textile variation from Polynesia & New Caledonia - Published : Feb 16, 2005

In French Polynesia, we have two variations of Conus textile Linné, 1758. The first one which I called "classic variation" represent the usual form of Conus textile which is common to many Pacific & Indian Oceans places. Of course they may vary like any genus though. By the way, in the Tuamotu Atolls, we have a local forma/variation wich is ver
