Bomba the Jungle Boy began in a series of boy's adenture books produced by the Stratemeyer Syndicate (the same folks who brought you the Hardy Boys, Nancy Drew, Tom Swift, the Bobsey Twins, and so many more characters) under the house name "Roy Rockwood." Many of the twenty books in the series were written by John William Duffield (although one on-line article posits Howard Garis as the main author).
From an advertisement from the original publisher: "Bomba lied far back in the jungles of the Amazon with a half-demented naturalist who told the lad nothing of his past. The Jungle Boy was a lover of birds, and hunted animals with a bow and arrow and his trusty machete. He had a primitive education in some things, and his daring adventures will be followed with breathless interest by thousands." Bomba, of course, was just one of the crowd following in the wake of the success of Tarzan. Others of that ilk included Maurice B. Gardner's Bantan (in the jungle islands of the South Pacific) and Harold Sherman's Tahara (whose adventures were set in some jungle and some some desert. as well as in the Yucatan). (Sherman had his greatest success as a psychic expert and exponent of ESP; he also wrote a long string of boy's sports novels and well as some simple-minded science fiction for Amazing Stories.) The Bomba books themselves were overtly racist. Bomba, being white had a fully engaged soul, the natives, being black, had souls that were "sleeping" -- but this at a time when such stereotypes were common in literature and accepted blindly by an enthusiastic juvenile audenience.

Here's the plot of Bomba on Panther Island, according to EBRzine.
"After the death of his pet monkey by a maurading panther, Bomba goes after the killer beast. Its trail leads him to Andy Barnes' home where architect Rob Maitland is trying to clear for an agricultural project. He has brought his sister Judy is [sic] with him to help set up the plantation, although she has no desire to stay. The panther kills two of the native workers, but their superstitious companions do not want the animal molested. The natives also believe that the servant girl, Losana, has the evil eye. Bomba takes an interest in Judy, but she wants no part of life in the jungle. When Rob accidently causes a forest fire, Bomba and the girl are forced into a cave where the jungle boy has to kill a panther. A rainstorm puts out a fire, and everybody learns a valuable lesson, including Judy, who decides to stay and help her brother."
Sadly, I couldn't find the film available online, although it occassionally pops up on TCM.
Without further ado, here's the Press Kit designed to promote the film:
* This certainly must be Crider's favorite.
