Twenty nine specíes ofGenus lnquisitor from Taíwan Waters are reported wíth synonymy, dìagnos況， distributíon, dímension, remarks and colored pictures 鱷 Among them, one new specíes, lnquisitor taivaricosa 組d 22 species are new records ofthe Taiwan Inquísìtors. KeyWord單: Inquísitor, Brachytoma, Thrridae, new record, n. sp., Taiwan. INTRODUCTION Jnquisitor and Brachytoma of 翎討 ids are dis仕ibuted in Indo-Pacific. Jnquisitor are mainly found in West Pacific from Australia to Japan and South African Waters. Brachytoma are mainly found in Tropical lndian Ocean from Oman, India to South China Sea. Taiwan is located at the mìddle of the v.乍到 Pacific Link and near the end of the Tropical Indian Ocean Link. Taiwan is also located in the subtropical zone between the Philippines and Japan. Hence, a lot of Jnquisitor and some Brachytoma from both temperate zone and tropical zone are available ín Taiwan Waters. The separation of Jnquisitor and Brachytoma is the first problem to be solved when FarnHy Turridae is separated into Farnilies Turridae, Clavid尉， Pseudomelatomidae and Mange1iidae (Chang 1995). lnquisitor andβrachytoma have similar protoconch and shell morphology, both Thiele (1929心 935) and Powell (1966) put them as synonymy. Some βrac equ凶lÏ 討s i扭 limbs 戶j oi泌ne叫d tωo forrn a central channel. Kilbum doubted that the teeth may be modified wishbone teeth (Taylor et al. 1993). If so, both lnquisitor and Brachytoma should be combined together into a sìn容le group. There are many genera such as lnquisitor, Funa" Pseudoinquisitor, Brachytoma, Ptychobela and Compsodrillia (Mammilaedrillìa) used for the group of shel1s whose conchological features are listed as follows: 1. Shell, medium sized, 11-65mm, elongate fusiforrn with tall spire of comparatively light built, 2. Scu1pture of stron忍 axials crossed by spiral cords and threads below a concave shoulder sulcus. Subsutural cord, strong, weak or obsolete. 3. Ape從ure ， narrowly ovate-pyriforrn contracted narrowly below to a short to moderately long anterior canal. Outer lip, thin with more or less a stromboid notch at the lower pa哎， 4. Sinus, U翩 shaped on shoulder slope with a parietal cal1us p揖 d. A dorsal varix, apart, near or at the sinus, 5. Protoconch, conical ofup to 5 smoo也 whorls ， usually 2刁 whorls ， 雀，瓜， 6. Color, white, yellow to chocola峙， mostly yellow, and ir--Eph-- 7. Opercul凶n ， leaf-shaped with terrninal nucleus. The type of radula of 也早 se species m益y be modified duplex or tubular, toxoglossate-like. Thiele •• (1929) located these shells under subfamily Brachytominae (now belonging to Mangeliidae). Powell (1966) put them under subfamily Clavinae (now Clavinae + Crassispirinae). In 1988, Kilbum put those having modified duplex radula into subfamily Crassisipirinae and in 1989, he found that the tubular radula of some shells 挂re forrned from two compone泌的 afo口至1 of modified duplex typ然 not 仕ue * :To whom correspondence and reprint requests should be addressed. 通訊作者:]6.文降，中央研究設動物研究所，靈北市南海區研究院路 2 段 128 號 14 C.

(1993) placed this group of shells under subfamily Crassispinae of Family Turridae but not under his Conid配合忽略 eliìdae + Conidae). It is so hard to separate those above mentioned 伊nera that many different genera have been used for a sin答 le species usually by the previous authors. In this papeζwe prefer use Inquisitor for all the other genera (Funa, Pseudoinquisìtor, Brachyton嗨 ， Ptychobe俗 ， Compsodrillia and Mammilaedrillia. MATERIALS and M 在 THODS After detail checkin各 and comparison the shell collections and liter器ture in the Malacology Lab. ，也e Institute of Zoology, Academia Sinica, Dr, C. K. Chang and some members of the Malacological Society of Taiwan, ROC多 29 species of Genus Inquisitor from Taiwan Waters are reported with synonymy, diagnos怒， distribution invento哼， dimension remarks and colored pictures. 快ESU L.:τSand 口 ISCUSSION Only 5 species of Inquistor were recorded from Taiwan area, such as flavidu旬 ， jeffreysii, kurod衍， 如 wamurai and vexillum (Kuroda 1941 , Habe and 哀。suge 1966). In 街坊 paper ， we reported 22 new records and one new species of Inquistor from T.器iwan area, totally, 28 species of Inquistor could be fo滋滋 in the Taiw.an waters. The list of Taiwan Inquisitor 1.
