332 CRUISE OF THE NEPTUNE 



In a small piece of buff limestone: 

 BRACHIOPODA. 



1. Small shell of the type of Glassia, possibly the same as the 



Glassia variabilis, (Whiteaves) from the Silurian of the 

 Ekwan river district. 



2. Rhynchospira, sp. or Retzia, sp. A finely ribbed shell, not suffi- 



ciently well-preserved to be identified with any degree of 

 certainty. 



3. Conchidium, sp. a small and immature form of what appears to 



be the Conchidium decussatum, Whiteaves. 



GASTEROPODA. 



4. Murchisonia (Hormotoma), sp. indt. 



5. Loxonema, sp. An imperfect individual with seven whorls pre- 



served, having an apical angle of 10, and would require at 

 least three more volutions to complete the shell at this stage. 



") In impure limestone: 

 stone : 



BRACHIOPODA. 

 1. Strophomena (Rafinesquina) alternata, (Emmons) Conrad. 



Three valves of this species appear to be represented in this 

 small slab of rock, and exhibit the characteristic sculpture 

 and other surface characters. 



In cream-coloured dolomite: 



BRACHIOPODA. 



1. Camarotoechia, sp. possibly the same as the Camarotoechia 



elcwanensis, Whiteaves. 



OSTRACODA. 



2. A very large Ostracod, which is not in a good state of preserva- 



tion, but which, from its size and general characters appears 

 to be close to Isochilina grandis 



In a drab-coloured limestone. 



BRACHIOPODA. 



1. Strophomena, sp. of the type of Strophomena euglypha, Sow- 

 erby. The sculpture of this shell is very much like that of 

 Strophomena (Rafinesquina) alternata, Conrad.
