Catfish Swallow Tail?

Hey I got this new 6’0 Hawaiian Island Creations board with a swallow tail variation i’ve never seen before. The cut in the tail is smaller and the inside cut is round. Some one referred to it as a Catfish Swallow but i haven’t seen anything else in stores or on the web about a catfish swallow. If you know the real name of this mysterious swallow tail please drop a response! Just wondering for curiousity’s sake. -Brian
