674 " THETIS " SCIENTIFIC RESULTS. 



of these species, Gonipsometra loveni, Ptilometra mulleri, and 

 Comanthus trichoptera, the other two being included on the 

 basis of the " Challenger" Report, they having been dredged by 

 that ship at Station No. 164 off Port Jackson. 



Mr. Whitelegge's list is of interest as being the first contri- 

 bution to the study of the Australian Orinoids, by one who was 

 actually acquainted with them in life ; and also as giving the 

 first definite data in regard to their breeding season. 



In 1890 Dr. P. H. Carpenter identified for the Port Philip Bio- 

 logical Survey Committee some twenty-nine speciaiens of Con)a- 

 tulids which had been dredged by Mr. J. Bracebridge Wilson in 

 the outer harbour at Port Phillip, and outside the Heads in the 

 summer of 1887-8. There were five species in this collection, the 

 most numerous being the little Compsonietra loveni, Comanthus 

 trichoptera, and I'tilonietra mulleri were also included, while 

 " Ayitedon iv'dsoui," the young of tliis last, and a new species of 

 ^^ Antedon" were recorded. Of this new species Dr. Carpenter 

 remarks that, though he believes it to be a new species, " it may 

 turn out to be only a strongly marked variety of A. pumila" (i.e., 

 Compsometra loveui). This new species is without doubt the 

 Compsoinetra lacerlosa described herein. 



In 1890 Dr. E. P. Ramsay recorded some specimens of Antedon 

 pumila [Compsometra loveni) which he obtained by dredging in 

 Port Jackson. 



The year 1891 was marked by the appearance of Dr. Clemens 

 Hartlaub's excellent Monograph upon the Comatulid fauna of the 

 Indian Archipelago, a preliminary notice of it having appeared 

 in 1890, primarily a report upon the magnificent collections 

 made by Dr. J. Brock at Amboiua, but including all the known 

 Crinoids of the Indian Ocean. In addition to Ftilometra mulleri 

 from Sydney, seven Australian Comatulids are considered, four of 

 which are here described for the first time, while one of the 

 remaining three is new to Australia ; these species are : — 

 Antedon nematodon (n.sp.) ... lieterometra nematodo7i 



Afitedon monacantha (n.sp.) ... Stephanortielra monacantha 

 Antedon tenera (n.sp.) ... ... Dichrometra tenera 



Antedon afra (n.sp.) ... ... Tropiometra afra 



Actinom.etra pectinata ... ... ? C omcltula jnirpurea 



Actinometra brachiolata ... Gomatula brachiolata 



Actinometra hennetti l ... ... C omanthus hennetti 



These four new species were all obtained many j^ears before by 

 the ships belonging to the Godeffroys of Hamburg, and deiposited 

 in their private museum. Here they had been examined by 

 Professor C. F. Liitken, who had bestowed MS. names upon them, 

 but had never published any diagnoses of his new forms. After
