Im Jahre 1853 beschrieb Girarp unter dem Namen Stimpsonia aurantiaca ein an der 
Küste von Süd-Carolina bei Charleston gefundnes Thier, das er für eine Nemertine hielt, in 
folgenden kurzen Sätzen: 
»Genus Stimpsonia, Girarv. Body elongated, subeylindrical or compressed, provided 
»with an expanded back, on the surface of which blood-vessels are observed, as in Acteons. 
»Cephalic region marked with an annular and smooth membrane, overlapping the anterior part 
»of the body. A broad, terminal and subeircular opening communicating with the general 
»cavity of the body, and through which the products of the general« [Druckfehler für »genital «?] 
»apparatus find their way outwards. At the upper margin of the cephalic ring there is a 
»funnel-shaped or rather corolliform organ somewhat like the corolla of the dragon root 
»(Arum) in the centre of which a cylindrical proboscis may be seen, at the inferior part of 
»which the mouth opens. The animal sucks its food through this proboscis, and the surrounding 
»disc assists in adhering to its prey. There are no eye specks. 
»7. Stimpsonia aurantiaca, GiRARD. Body compressed laterally: transverse diameter about 
»a quarter of an inch; depth greater than the horizontal diameter. Periphery of the anterior 
»opening undulating. Length of the body about six inches, and probably attaining a large 
»size. Ground color of a bright purplish or greenish hue with numerous irregular transverse 
»bands of bright golden. 
»Found at low water mark in holes descending perpendicularly into the sand. Fort 
»Johnston, 8. C.« 
Es ist das Verdienst Verrırrs, in dieser Beschreibung den Balanoglossus erkannt zu 
haben. Man kann dem Genannten nur zustimmen, wenn er erklärt, »no one can doubt that 
this species was a Balanoglossus« (1873 Nr. 89 p. 234), denn die Schilderung lässt sich in 
allen Punkten auf einen solchen deuten, allerdings unter der Annahme — die ja aber durchaus
