The close resemblance between the skin of Goeldi's marmoset ( Callimico goeldii ) and that of the genus Saguinus (Hoffmannsegg) suggests that C. goeldii be placed in the family Callithricidae (Thomas, '03) as originally proposed by Pocock in 1920 and not in the family Cebidae (Swainson, 1835). Recent karyological evidence supports this point of view. The skin is characterized by (1) a melanin‐laden epidermis and aggregates of melanocytes in the upper dermis; (2) nonglandular skin in the gular region distinguished by a sparsely haired, pebbly, granular surface; (3) cholinesterase‐positive Meissner corpuscles and papillary nerve end‐organs; (4) groups of 3 to 5 hair follicles in linear perfect sets; (5) sinus hairs on the ventral ulnar wrist; (6) manubrial, sternal, genitopubic, and circumanal sebaceous‐apocrine glandular concentrations rich in phosphorylase and alkaline phosphatase; (7) eccrine glands, restricted to volar friction surfaces, whose clear and dark secretory cells contain phosphorylase but no glycogen; and (8) eccrine glomeruli surrounded by many acetyl‐ but few butyrylcholinesterase‐reactive nerves.
