W. Stimpson, labelled “ type”; dry.    Typelocality. USA, Florida: off Sand Key Light, 125 fm (  229 m) ( Fraser 1943a).  Current status.Valid.   Remarks.The original description of  Sertularella humilisby Fraser (1943a), in a collection from the MCZ, was based on a single colony said to reach 1 cmin height. A specimen of the species from the typelocality at that museum (MCZ-IZ 9008), containing a label marked “ type”, is the holotypeby monotypy (ICZN Art. 73.1.2) because no other typematerial is known to exist. The specimen is now dry, accompanied by a note stating “found dry (prior to 1983)”. Although desiccated and in quite poor condition, the base of the colony nevertheless matches the illustration provided by Fraser (1943a, pl. 19, fig. 12). Gonophores were lacking in the hydroid described by Fraser (1943a), and the small, unbranched colony appears to have been a juvenile.  Sertularella humilis, taken to be valid in WoRMS, is known only from the original description. Fraser (1947a)speculated that its affinities were with  S. tenella(Alder, 1856)and  S. rugosa( Linnaeus, 1758), both boreal species. 1915525929 [199,1115,1874,1899] United States of America 229 Sand Key Light 47 48 1 Florida holotype
