He is best known for his
anatomical and histophysiological investigations of
arachnids, that included intensive studies involving the
silk glands of the genus
Scytodes (spitting spiders). He also described
metamerization in
Chelicerata, and performed
systematic reviews of various spider families —
Sicariidae,
Pholcidae,
Thomisidae and
Salticidae. In late September 1953, a coelacanth was caught in waters near the port city of
Mutsamudu,
island of Anjouan (third discovered specimen overall). In 1958 he published a treatise on the anatomy of the coelacanth, titled
Anatomie de Latimeria chalumnae. Taxa with the specific epithet of
milloti honor his name; examples being
Paracontias milloti Angel, 1949 (Nosy Mamoko
skink), and
Platypelis milloti Guibé, 1950 (Millot's froglet). With
Lucien Berland, he described numerous species of spiders and the arachnid genera
Afraflacilla and
Bacelarella. == Published works (selection) ==
