Description:Excerpt from Siboga-Expeditie: The Chaetognatha of the Siboga Expedition, With a Discussion of the Synonymy and Distribution of the Group The Material Collected, And Its Preservation. The material received, amounting to thousands of specimens, was contained in a few tubes of most beautifully preserved specimens in Formalin, and in a large number of tubes of alcoholic specimens very much less well preserved. To have identified every specimen with accuracy would have required years of close application, and the results which might have been expected from this procedure would, apparently, not have been commensurate with the labour involved. The Formalin specimens were therefore studied first of all with considerable care, until the species represented in this material were thoroughly familiar; afterwards a good deal of the determination was done under a dissecting lens; and only doubtful or unfamiliar specimens were put under the microscope, measured, and counted. Had not the formalin material been available, and been carefully studied, the determination of the Alcohol material would have been in most cases almost impossible; the fins and corona ciliata had generally entirely disappeared, the body had become shrunken and distorted, thus giving a disproportionately large appearance to the head, and the opacity of the tissues made the counting of the teeth both difficult and uncertain.
