ABSTRACT. Some fasciolariid species of the eastern Pacific Ocean from western Mexico to Alaska are discussed, with the description of the new genus Araiofusus gen. nov. and nine new species: Fusinus edjanssi sp. nov. from Cedros Island, Pacific coast of Baja California to San Hipolito Point, Pacific coast of Baja California Sur, Mexico; Fusinus laticlavius sp. nov. from deep water off Danzante Island, western Gulf of California, Baja California Sur, Mexico; Fusinus seriatus sp. nov. from the Pacific coast of Baja California Sur, Mexico; Fusinus euekes sp. nov. from the eastern Gulf of California, Mexico; Araiofusus araios sp. nov. from deep water in Monterey Bay to the Gorda Bank off Cabo San Luca, Mexico; Araiofusus eueides sp. nov. from Monterey Bay to Orange County and Catalina Island, south to Cedros Island, Pacific Baja California, Mexico; Harfordia chucksnelli sp. nov. from the Channel Islands and off Santa Barbara; Harfordia mcleani sp. nov. from Monterey County throughout the Channel Islands and south to Cedros Island and Barbarofusus guadalupensis sp. nov. from Guadalupe Island, Pacific Baja California, Mexico. A new name, Hesperaptyxis meridionalis, is proposed to replace the homonymous name Latirus melvilli Dall and Ochsner 1928 non Schepman, 1911, a Pliocene species from the Galapagos Islands. A lectotype is selected for the Recent species Fusus luteopictus Dall, 1877, and a neotype for the Pleistocene species Fusus barbarensis Trask 1855, the type species of Barbarofusus. Types of the previously-named species here assigned to Araiofusus, Harfordia and Barbarofusus are illustrated. Four new combinations are introduced: Araiofusus colpoicus (Dall, 1915), Harfordia arnoldi (Cossmann, 1903), H. robusta (Trask, 1855) and Barbarofusus kobelti (Dall, 1877). Most of the smaller fusinine species from this area not dealt with here were assigned to the genus Hesperaptyxis in a previous paper (Snyder and Vermeij, 2016).

来自加利福尼亚南部和墨西哥西部的片蚴科（腹足纲：Buccinoidea）的一个新属和九个新种

摘要。讨论了从墨西哥西部到阿拉斯加的东太平洋的一些片状藻类物种，并描述了新属 Araiofusus gen。十一月 和九个新物种： Fusinus edjanssi sp。十一月 从下加利福尼亚州太平洋海岸的塞德罗斯岛到墨西哥南下加利福尼亚州太平洋海岸的圣伊波利托角；Fusinus laticlavius sp. 十一月 来自墨西哥南部加利福尼亚湾西部丹赞特岛的深水；Fusinus seriatus sp. 十一月 来自墨西哥南下加利福尼亚州的太平洋沿岸；Fusinus euekes sp. 十一月 来自墨西哥加利福尼亚湾东部；Araiofusus araios sp. 十一月 从蒙特雷湾的深水到墨西哥卡波圣卢卡附近的戈尔达银行；Araiofusus eueides sp. 十一月 从蒙特雷湾到奥兰治县和卡塔利娜岛，南到墨西哥太平洋下加利福尼亚州的塞德罗斯岛；Harfordiachucksnelli sp. 十一月 来自海峡群岛和圣巴巴拉附近；Harfordia mcleani sp. 十一月 从蒙特雷县到整个海峡群岛，南到塞德罗斯岛和 Barbarofusus guadalupensis sp。十一月 来自墨西哥太平洋下加利福尼亚州瓜达卢佩岛。一个新名称 Hesperaptyxis meridionalis 被提议取代同名 Latirus melvilli Dall 和 Ochsner 1928 non Schepman, 1911，一种来自加拉帕戈斯群岛的上新世物种。1877 年为近代物种 Fusus luteopictus Dall 选择了一个选型，为更新世物种 Fusus barbarensis Trask 1855 选择了新型，Barbarofusus 的模式种。图中显示了此处指定给 Araiofusus、Harfordia 和 Barbarofusus 的先前命名物种的类型。引入了四种新组合：Araiofusus colpoicus (Dall, 1915)、Harfordia arnoldi (Cossmann, 1903)、H.robusta (Trask, 1855) 和 Barbarofusus kobelti (Dall, 1877)。在之前的一篇论文（Snyder 和 Vermeij，2016 年）中，这里未涉及的该地区的大多数较小的 fusinine 物种被归入 Hesperaptyxis 属。
