Hyndman from Belfast was mainly interested in marine zoology and marine botany (particularly molluscs and algae). His specimens of both groups may now be found in the Ulster Museum the algae in the Herbarium.In his early years Hyndman formed an insect collection (now in the same repository) and clearly had an interest in all ascpects of local natural history.
He was also a founder member of the Belfast Natural History Society and contributed to S.A.Stewart and T.H.Corry's Flora of the North-east.
Anapagurus hyndmanni (Bell ,1845) as well as A. laevis and Pagurus cuanensis were also discovered by Hyndman at Portaferry (and Bangor) and named by Thompson (q.v.) without formal descriptions.
