Summary:

Has sent off specimens of Virgularia but fears they are in bad state. He could not find his dried specimens. Encloses notes that can be relied upon but may be of little use.

Also encloses a memorandum for Prof. K. G. Semper.

CD thinks Alcide d’Orbigny may have given name of Virgularia patagonica.

CD enjoyed RAvK’s recent visit [see 7164].

Summary:

Thanks for RAvK’s work [Anatomisch-systematische Beschreibung der Alcyonarien, pt 1, Die Pennatuliden (1870)].

Asks whether muscles to quills of porcupine are striped. Are they homologous to muscles of ordinary hairs? Could unstriped muscles develop into striped?
