No. 3.— On the Eyes, the Integumentary Sense Papille, and the 
Integument of the San Diego Blind Fish (Typhlogobius cali- 
Jorniensis, Steindachner). By W. E. Rırrer.! 
Tun work the results of which are embodied in the present paper 
was begun and well advanced at Harvard University, and has been 
completed at the University of California. 
I wish here to express my warmest appreciation of the many kind- 
nesses received at the hands of Prof. E. L. Mark, not only during my 
residence in Cambridge as a student under him, but particularly since 
leaving there. I have also to thank Prof. C. H. Eigenmann both for 
specimens sent me from San Diego while I was working in Cambridge, 
and for valuable information and suggestions about collecting the fish 
during my visit to San Diego last summer. 
Typhlogobius californiensis was first described by Dr. Franz Stein- 
dachner. The species is the type of the genus, and thus far is the 
only one known. — Steindachner's (79, pp. 142, 143) description of the 
eyes is as follows: “Die winzig kleinen, wie Punkte durchschimmer- 
enden Augen, liegen hoch am Seitenabfalle des Kopfes gegen Ende des 
ersten Viertels der Kopflänge ; ihre Entfernung von einander steht der 
Schnauzenlänge nach und beträgt circa 4 der Kopflinge.” According 
to this author the genus resembles Crystallogobius, Gill, from which it 
differs in its dentition and abortive eyes. 
Miss Rosa Smith (81, pp. 19-21), — now Mrs. C. H. Eigenmann, — 
unaware that the fish had been described by Steindachner, redescribed 
it, making for it, as the Vienna ichthyologist had done, a new genus, the 
name of which was derived from the rudimentary condition of its eyes. 
Othonops was the generic name given it by Miss Smith, and this term, 
signifying as it does “veiled or obscured eyes,” is, so far at least as the 
younger individuals are concerned, undoubtedly more nearly true to the 
facts, as the sequel will show, than is the name chosen by Steindachner, 
Typhlogobius signifying “blind goby.” The specific name chosen by 
Miss Smith was eos. She says: “This species is most closely related to
