Grammaria rigida Fraser, 1943a 

Grammaria rigida Fraser, 1943a: 79  , pl. 18, fig. 8.

Holotype. MCZ-IZ 9011: Barbados, off Sandy Bay, Hassler Expedition 1871–1872, 13°03’00”N, 59°35’00”W, 29–30 December 1871, one colony fragment, 1 cm high, in fair condition, without gonophores, labelled “ type ” and “ holotype ”; 80% ethanol.

Type locality. Barbados: off Sandy Bay , 13°03’00”N, 59°35’00”W, 100 fm (183 m) ( Fraser 1943a).GoogleMaps 

Current status. Valid.

Remarks. Grammaria rigida  was described by Fraser (1943a) from a colony fragment in a collection at the MCZAbout MCZ. Although no types of it were originally designated in that paper, material of the species exists at the museum (MCZ-IZ 9011) from the type locality, and with labels marked “ type ” and “ holotype ”. No other types are known to exist, and the single specimen, a fragment of a hydrocaulus with 13 hydrocladia or parts thereof, is the holotype by monotypy. It is in satisfactory condition, although hydranths are mostly deteriorated or absent.

This is another poorly known hydroid species, described by Fraser (1943a) from the trophosome only. No records of it have been published since the original description, although non-type material from North Carolina, identified as G. rigida  , exists at the NMNHAbout NMNH ( USNMAbout USNM 61370, USNMAbout USNM 61371, USNMAbout USNM 72875). The species is listed as valid in WoRMS.
