Restoration of the Holotype of Proconsul nyanzae
Folia Primatologica, 1978The crushed palate and lower face of the holotype of Proconsul nyanzae has been prepared using the acetic acid technique. The prepared and conserved fragments have been restored to their natural positions using a synthetic cement and polyethylene glycol wax (Carbowax 4000) to fill the gaps.

Science, 1960
The description of new species should not be confined to physical description of a holotype. One specimen cannot include all characters or be typical of any taxon. The holotype serves only a nomenclatural function and might also be termed the name-bearer (nomenifer) to avoid confusion of "type specimen" with "typical specimen."

Holotypes in the taxonomy of planktonic foraminiferal morphospecies
Marine Micropaleontology, 2011Abstract The claim that holotypes serve as exemplars of morphology is examined in the context of planktonic foraminiferal taxonomy. A review of some species described over the past 90 years suggests that holotypes are selected subjectively, presumably guided by authors' conceptions of diagnostic characters.

THE HOLOTYPE OF HYMENOCALLIS PALMERI
TAXON, 1956The writer resided in Florida from 1930 to 1940 and he often encountered Hymenocallis palmeri in the wild, particularly on the west coast of peninsular Florida, from Collier to Pinellas counties. Seeds and bulbs were sent to Major Pam in England for study in the 1930's. Thus there was no question as to its existence.

Not a Lycogala? Investigating the holotype of Lycogala fuscoviolaceum
European Journal of ProtistologyThe myxomycete Lycogala fuscoviolaceum was described by P. Onsberg in 1972 based on a single specimen collected in Nepal. The status of this species remains ambiguous, as no additional findings have been reported since its description. In this study, we re-examined the holotype stored in Copenhagen to determine the true systematic position of L ...

Gonnardite; re-examination of holotype material and discreditation of tetranatrolite
American Mineralogist, 1999Gonnardite is a fibrous zeolite. Its chemical variability and the frequent close association with thomsonite and other zeolites have made the chemical and crystal structural definition of the mineral difficult. Only recently was the structural relationship to natrolite confirmed unambiguously by single crystal X-ray diffractometry. The present chemical
