Гелицид сымалдуулар (лат. Helicinidae) — үлүлдөрдүн бир тукуму.
Helicinidae is a family of small tropical land snails which have an operculum. They are terrestrial operculate gastropod mollusks in the superfamily Helicinoidea.
These snails are not at all closely related to the air-breathing land snails, despite a superficial similarity of the shells. The name "Helicinidae" immediately reminds most people of "Helicidae", the most popular group of land snails including e.g. Helix pomatia, but the important two letters "ni" only from the Latin diminutive of the latter name alluding to superficial similarities of otherwise completely different things.
These snails are found in tropical and subtropical areas but they have an odd distribution: they are restricted to the Caribbean islands and some Indo-Pacific and Pacific islands, as well as the edge of the Asian and Australian continents. Some species are found in the southern United States, from Louisiana to Florida; others in Central and South America.
Helicinidae belongs to superfamily Helicinoidea according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).[2]
This family consists of six following subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):
Genera within the family Helicinidae include:
Subfamily Helicininae
subfamily Ceratodiscinae
Subfamily † Dimorphoptychiinae
Subfamily Hendersoniinae
Subfamily Stoastomatinae
Subfamily Vianinae

Helicinidae é uma família de caramujos terrestres encontrados em regiões tropicais do Caribe e várias ilhas do Pacífico.
Esses animais não pertencem ao grupo dos Pulmonata, os caracois e lesmas terrestres. São na verdade caramujos marinhos que recentemente abandonaram o mar para colonizar o meio terrestre. Destinguem-se dos caracois terrestres comuns pela presença de opérculo e olhos na base das antenas, não na ponta.[1]

樹螺科(學名:Helicinidae),又名䗉螺科[2][3]、䗉蝸牛科[4][5]或無臍蝸牛科[6],是軟體動物門腹足綱之下的一個科,舊屬蜑螺總科(Neritacea),今獨立出來成為樹螺總科之下唯一的一個科。本科的物種在其殼口均有厣可封蓋其殼。皆為陸生。
雖然本科物種在外表跟陸地上呼吸空氣的蝸牛很相似,但其實在分類學來說,兩者的分歧頗大。
本科物種的分佈比較奇怪:牠們生活於熱帶及亞熱帶地區,但只限於加勒比海的島嶼及部份印度太平洋區及太平洋的島嶼,也在亞洲及澳大利亞大陸的邊緣地區生活。
本科估算約有770-1400個物種。
根據2005年《布歇特和洛克羅伊的腹足類分類》的分類,本科由蜑螺總科之下轉為成立獨立的一個總科[7]。本科由六個亞科組成,分別如下:
本科的屬計有:
樹螺亞科 Helicininae
subfamily Ceratodiscinae
Subfamily † Dimorphoptychiinae
Subfamily Hendersoniinae
Subfamily Stoastomatinae
Subfamily Vianinae
