same depths. From the former we now have Astroschema salix and Iwrridum, 

 (?) Ophioceramis clausa, OpJdactis cuspidata, O. Jlexuosa, 0. nama, Amphiura 

 canescens, A. argentea, A. bellis, Ophiomitra plicata, Ophiacantha cornuta, 0. ve- 

 pratica, Ophiophyllum petilum, Ophiochiton lentus, Ophiomusium scalare, Ophi- 

 oconis pulverulenta, Ophiopyrgus Wyville-Thomsoni, Ophiopyren hrevispinus, 

 Opliiozona insularia, and Ophiomyxa australht. Of these Ophiophyllum petilum, 

 Ophiacantha vepratica, and Ophioconis pulveridenta correspond very closely 

 with the Ophiophyllum above mentioned, with Ophiacantha Bairdi, and with 

 Ophioconis miliaria. In both faunaj is found exclusively the peculiar genus 

 Ophiopyren, and Ophiozona exists in both. Ophiomusium scalare and Ophio- 

 mitra plicata stand^ pretty near Ophiomusium testudo and Ophiomitra chelys. 

 The genus Astroschema, so richly represented in the West Indies, has two 

 species in this list of twenty. As a contrast comes the extraordinary form 

 Ophiopyrgus, known thus far only from the neighborhood of the Fijis. It 

 remains for future dredgings to show whether these resemblances result proba- 

 bly from community of origm, or simply indicate the presence of a nearly 

 identical fauna over vast tracts of deep-sea bottom.
