title: Ureotelism in the slug, Limax flavus Linné.
abstract: The slug, Limax flavus, excretes both urea and purines. 1. Urea and purines account for up to 59 and 41% of the excretory nitrogen, respectively. 2. Of the purines excreted uric acid predominates (64%) with quanine (22%) and xanthine (14%) usually being voided in lesser amounts. Neither adenine or hypoxanthine was detected. 3. Urea was excreted in urine while the purines were deposited irregularly, as semi-solid, yellowish nubs.
