Rhynchocalamus melanocephalus (Gthr.) has been identified with Homalo- 
soma melanocepTialum (Jan) by Prof. Peters, who states that it ought to be 
referred to Coronella, with which it agrees in pholidosis and dentition. 
Berlin. Monatsber. 1869, p. 439. [The typical specimen of Rhynchocalamus 
is 17| inches long, and in excellent condition ; the rostral shield is produced 
backwards as in Simotes ,* there is one nasal shield only ; there are no teeth 
on the palate.]

Dromicus chamissonis (Wiegm.) occurs in the Gallapagos Islands, Peters, 
Berlin. Monatsber. 1869, p. 719. [The Recorder remarks that he can confirm 
Prof. Peters’s observation, having now seen a series of examples of this snake 
from these islands. There were two varieties, one very similar to the com- 
mon continental form, the other identical with the snake described by him 
from a young specimen under the name of Herpetodi'yas hiserialis. Some ex- 
amples were intermediate between the varieties, so that there is no doubt 
about their specific identity. The syncranterian character of the dentition is. 
not well developed in this species.]
