Roubaud (1914) hasrecently published an interesting article on thisdisease, in which he differentiates it from the creeping eruption due to the presence underthe skin of dipterous larvae. Incidentally he pointsout that (srbiss is a local name for the disease inSenegal, and that this accounts for the termlarbish employed by Berenger-Feraud. Larbish, or diseases of a similar nature, havebeen observed in a number of tropical countries,especially on the West Coast of Africa. In WestAfrica such affections have been described fromFrench Senegal, Sierra Leone, Liberia, and theCameroons, and the following brief record of a casewhich came under my observation in 1912, althoughit adds nothing to our knowledge of the pathology,proves that the disease occurs also in NorthernNigeria. The patient was a European man who cameunder observation in June, 1912, at Ilorin inNorthern Nigeria. On the dorsum of the right footat the base of the great toe there was a narrow. track or ridge forming several coils, which had ledthe patient to believe that he had a guinea-wormwhich had come to the surface in this situation,and was about to break through the skin. It hadbeen noticed that at the one end the track keptadvancing, whilst at the other it gradually fadedaway. The advancing end of the track was redlike a line of erythema, slightly raised, and felt asas if there was a piece of thin string under the skin;the intermediate part was more decidedly elevated,almost like a linear blister, with a zone of erythemaon each side, and the hinder end was dried up andin process of scaling off. Vesicles which containeda sero-purulent fluid had formed in the intermediatepart. When first seen the lesion was confined to thedorsum of the great toe. From tiiis position, in the course of a month, it advanced towards theinner margin of the fof)t, anfl then took a zigzagcoiuse across the sole and back again. The photo-graph, a
