MR. F. E. BEDDARD OIST THE ANATOMY OF [May 26^ 



galeus" but figures a state of affairs like, for instance, Dasyjnis 

 where there is no defined colic loop. It would be, as I think, 

 convenient to restrict the term colic loop to such a defined loop 

 as occurs in the genus Lemur ^ to which I shall now refer. 



Sir W. Flower has figured the single ansa coli in the genus 

 Lemur (in L. jJavifrons) and Dr. Klaatsch has figured an 

 identical loop in Hcqxdemur. and Dr. Mitchell (without referring 

 to Flower's figure oi' to that of Klaatsch) has figured an identical 

 loop in Z. mongoz, var. nigrifrons. They are indeed obviously 

 identical. I can confirm from my own dissections the existence 

 of this loop in L. mongoz, which seems to me to correspond to 

 the ansa coli dextra of Tullbeig, but of which the constituent 

 limbs were closer together than is figured by Mitchell, agreeing 

 therefore more closely with the figure of Flower. In L. macaco-

was the same ansa coli. In L. alhifrons again the same ; ibut 

 the two limbs were a little furthei- apart in both of two 

 examples. Lemur sclateri was the same. The oenus Galaqo 

 shows an interesting further development of this simple ansa of 

 Lemur. I have ascertained that this loop has been fioured 

 previously in Galago crassicaudata by Flower ; but I cannot accept 

 the figure given by Dr. Mitchell as representing the facts in even 

 an approximate fashion. I have lately examined two examples of 

 Galago garnetti (the species described by Dr. Mitchell), and some
