In this short communication it is my purpose to call attention only to that form of spasm of the infantile larynx due to a congenital valvular formation of the upper orifice of the larynx, a condition that is sometimes overlooked as a cause of noisy respiration in children.
In these cases there is a laryngismus of a mild variety, and as it is so very persistent, it is evident that it must depend upon some local cause. The subjects of this condition may be perfectly healthy, showing no evidences of rickets or glandular enlargement—the most common causes of that severe form of laryngeal spasm known as laryngismus stridulous.

The spasm is more persistent than in the severer forms of laryngismus, being present to some extent during sleep, and
