In another place Aldrovandi gives a figure of the 

 spinous Eeversus, but in his account of this form he gets 

 his data badly mixed since much of it is the data which 

 Peter Martyr ascribes to the anguilliform variety. In 

 neither account does Aldrovandi offer anything new. 



We now come to a Spanish work published in Mexico 

 City five years before the Pilgrims landed on Plymouth 

 Eock and when Jamosto^vn was but eight years old. This 

 is Hernandez's work (1615) on the nature and virtues of 

 the plants and animals used in the practise of medicine 

 in New Spain. How he brings in the Remora is not 

 clear, but he attributes his account to Oviedo, the actions 

 of whose anguilliform Eeversus he describes in his 

 ( Oviedo 's) own words. However when he attempts to 

 further describe the fish he gets his account tangled up 

 with that of the porcupine fish. He does not seem to 

 have ever seen either fish. 



In 1635, Joannes Eusebius Nieremberg, a Jesuit priest, 

 who was professor of physiology in the Eoyal Academy 

 of Madrid, published his ''Historia Naturae" in folio 

 form. This is a compilation of not very great value, the 

 less so because the references are not set forth clearly. 

 Our interest in his book, in which he quotes Peter Martyr, 

 Oviedo, Hernandez and another to be referred to later, is 

 chiefly centered in his figure of the Eeversus or Guiaca- 

 nus. This is reproduced here as Fig. 6, Plate II. This 

 is plainly Gesner's figure with the addition of a sort of 

 saw-toothed mane on the anterior dorsal region. 



Ogilby, whose huge tome was published in 1671, had 

 evidcnfly iicvci- seen the Guiacan, but he inserted on page 

 40 (»!' Aiii. i ica" such a quaint and interesting figure 

 of his (-(uicrption (or his artist's) of how this fishing was

Tlw Dntdn.iaii, Th. van r.ni.sM, in 17l>!i piihlishrd a 

 very interesting account of the KN'Vcrsns: but a careful 

 translation of his Dutch shows that it is but a translation 

 of Martyr and Oviedo, and further that he confuses the
