REMARKS

Two specimens (MNHN-ZM-MO-1992-112, MNHN-ZM-MO-1992-111) are attributed to G. crassicaudatus but none of these has a complete skull or are adult. This species is characterized by a medium size (GLS> 24 mm and < 32mm) ( Monadjem et al. 2015), a rufous pelage, and proodont upper incisors. The nasal bone of this species is narrow and does not extend onto the intermaxillary bone and molar rows are larger than in other Gliridae species.Neither Gautun et al. (1986) nor Coe (1975) recovered it on Mount Nimba. Grubb et al. (1998) indicated its presence in Togo and Ghana, while the holotype came from the Du Queah river in Liberia. According to Heim de Balsac & Lamotte (1958), the juvenile specimen attributed to this species is distinguished from G. lorraineus by a very wide interorbital constriction and braincase, and more rounded zygomatic arches. According to these authors this specimen fits well with G. crassicaudatus described from Bouroukerou ( Côte d’Ivoire). Specimen MNHN-ZM-MO-1992-112 has a very broken skull, nasals are not preserved but the four molars are erupted. The CIO corresponds to the average values of G. lorraineus but the upper and lower teeth rows are larger ( Table 12 ). The specimen MNHN-ZM-MO-1992-111 is also a juvenile whose upper molars are not all erupted; its incisors are orthodont and the nasal is not extended and narrow. Its CIO corresponds to G. murinus other specimens and the skull is smaller than in other specimens but the lower molar row is larger.
